I have a problem with using virtualenv and django in bash. If I type python -m venv env in cmd, then env\Scripts\activate, and then virtualenv - I get 'virtualenv' is not recognized as an internal or external command, operable program or batch file.. If I do the same in bash I get bash: virtualenv: command not found. How do I fix this?
Try the following to resolve your issue.
Check all of the environment variables related to the software you require to be used at least.
Check the permissions for files and folders for the software.
Sometimes uninstalling and installing the software with issues can solve problems quickly.
If you have performed number 2. and you are still have errors, proceed to number 3.
You may have dependencies missing, a good tool i have used on Windows is Dependency Walker, and the software will check if any file and dependencies are missing, and you should be able to download them.
An error message may output a file is not found but in fact a dependency is missing, relating to the software you are trying to run.
Try the following steps in the terminal, it may solve your problem.
using terminal, mkdir to make a directory for your project
cd to your project folder/dir
type pip3 freeze, it will show up all the installed packages and dependencies on global scope/system
but we gonna have a venv where we will install our necessary packages and dependencies
type python3 -m venv ./venv to create venv inside your current project folder, please ensure you are inside the folder before running this command
[if you are not using python 3, then the command will be python -m venv ./venv]
to actiavte environment,
on mac, run source ./venv/bin/activate ||
on windows, run .\venv\Scripts\activate.bat [if it doesn't work, try to put your absolute path]
you can check what is installed inside venv using pip freeze, you will see nothing inside the venv
Now you can install django inside venv for your project
to deactivate the environment, just type deactivate
I try this command:
$ virtualenv .venv
$ sourse .venv/bin/activate
(.venv) $ pip3 install django
The last command installed the django3 on the whole system while the virtual machine was active and should only be installed on the virtual machine. why??
I tried django-admin stratproject mysite, but I received this error:
Command 'django-admin' not found, but can be installed with:
sudo apt install python-django-common
so, I try sudo apt install python-django-common. Then again try django-admin stratproject mysite and resived error: Cannot find installed version of python-django or python3-django.
how I can solve this problem??
Did you add a Python path. If you have, you can enter the Python terminal when you write Python. You can see the installed libraries by typing pip freeze.
The Django is not added in your python path , if you still want to run your code go to python directory and then run the django-admin command.
Go to the folder where your python is installed and open terminal there
after that run your command
django-admin startproject test
Try using pipinstall django instead of pip3 install django in virtualenv.
By running virtualenv .venv you have created local python environment with current default system version of python (i.e. on older distributions this might be python 2.7)
While activating virtual environment, it replaces some ENV variables to allow python to address this local environment, but not system one.
pip is one of them. pip inside virtualenv points to virtualenv's pip. Virtualenv might not redefine pip3 command - this is only needed system-wide, cause you may have many different versions of python in the system at the same time. And as far as virtualenv has only one version of python / packages inside - where is no need for it to redefine pip3.
Running django-admin startproject test inside virtualenv uses virtualenv's python packages, and if there is none, it may actually use system-wide packages, but it depends on the options virtualenv was created with (use system pacakges), PATH variables etc.
Also, try not to install or rely on system-wide packages - use virtuelnv.
Using virtualenv is good, and there is a lot of helpers to ease - pipenv, virtualenwrapper etc
Just run this in the command line.
apt-get install python3-django
Hope this will solve your problem.
While I was trying to execute the mkvirtualenv command on the command prompt, I was getting this error:
C:\Users\mukesh>mkvirtualenv myproject
'mkvirtualenv' is not recognized as an internal or external command, operable program or batch file.
For Python 3.3 or newer, Commands for installing, creating and activate virtual environment has been changed.
You can install virtual environment using pip:
py -m pip install --user virtualenv
For creating new environment:
py -m venv myproject
To activate your virtual environment:
.\myproject\Scripts\activate
After activating virtual environment, You’ll see “(myproject)” next to the command prompt.
You may find this link useful, as it shows the steps required. It is possible you have simply missed the earlier steps, leading to the error.
The below information is from: https://docs.djangoproject.com/en/2.2/howto/windows/
This will run you through the creation of a virtual environment on Windows:
Install virtualenv and virtualenvwrapper¶
virtualenv and virtualenvwrapper provide a dedicated environment for each Django project you create. While not mandatory, this is considered a best practice and will save you time in the future when you’re ready to deploy your project. Simply type:
pip install virtualenvwrapper-win
Then create a virtual environment for your project:
mkvirtualenv myproject
The virtual environment will be activated automatically, and you’ll see “(myproject)” next to the command prompt to designate that. If you start a new command prompt, you’ll need to activate the environment again using:
workon myproject
To create a virtual environment,
decide upon a directory where you want to place it, and run the venv module as a script with the directory path:
python3 -m venv tutorial-env
This will create the tutorial-env directory if it doesn’t exist, and also create directories inside it containing a copy of the Python interpreter and various supporting files.
A common directory location for a virtual environment is .venv. This name keeps the directory typically hidden in your shell and thus out of the way while giving it a name that explains why the directory exists. It also prevents clashing with .env environment variable definition files that some tooling supports.
Once you’ve created a virtual environment, you may activate it.
On Windows, run:
tutorial-env\Scripts\activate.bat
On Unix or MacOS, run:
source tutorial-env/bin/activate
some times the environment will not active because users are not allowed to run scripts in the current system so you should
-go to windows PowerShell
-run as administrator
-then past this code
-Set-ExecutionPolicy -Scope CurrentUser Unrestricted
now you are allowed to run scripts on your system
then try this again
py -m pip install --user virtualenv
For creating new environment:
py -m venv myproject
To activate your virtual environment:
.\myproject\Scripts\activat
If you have a Windows computer (and installed the Windows version virtualenvwrapper-win), make sure you add the Scripts folder to the path. As per the installation instructions:
To use these scripts from any directory, make sure the Scripts
subdirectory of Python is in your PATH. For example, if python is
installed in C:\Python27, you should make sure C:\Python27\Scripts is
in your PATH.
Here's some decent instructions on how to edit your path. Nowadays you can probably create a new entry after selecting to edit the path environment variable. That new entry should just be the location of the Scripts folder (including the Scripts folder). No need to add semicolons to a super long path name - it generally does that for you nowadays. You'll probably have to restart your computer for it to take effect.
You can find out where your Python is installed here. If you are on Windows and installed Python via the Microsoft Store, you won't see a Scripts folder. In that case, install Python from the Python website, not from the Microsoft Store.
I downloaded the necessary files from the link https://github.com/django/django.git and pasted them in to my virtual env directory
After setting up and activating the virtualenv, when I run the following command:
$ pip install -e django/
It produces this error:
(ENV) C:\WINDOWS\system32>pip install -e django/ django/ should either
be a path to a local project or a VCS url beginning with svn+, git+,
hg+, or bzr+
I am a Windows user. I think the command is for bash not for cmd.
Is it necessary to use this git tool to finally work with django ?
As instructed on the Django website :
If you're just starting out with Django development I'd recommend looking at some YouTube videos before jumping into the Django docs. Personally when I was starting out I found that the docs were quite hard to understand in the beginning, but as you get better you can refer back to them more and more.
Here's a good beginner video series to get you started.
In any case, I would recommend using virtualenvwrapper-win so that you can work on multiple Django projects without any conflicts.
First, ensure that you have added Python to the Windows environment. Open CMD and run pip install virtualenvwrapper-win.
Then cd to whichever directory your project files will be in and run mkvirtualenv projectname.
Finally run setprojectdir path/to/folder
Now whenever you want to enter that virtual environment and work on your project all you have to do is run the command workon projectname and it'll do the rest for you. You'll know it worked if on each new line in the command prompt it gives you (projectname) in brackets.
To actually install Django all you need to run is pip install django while in the virtual environment.
From your question, I suppose that you are trying to install django inside your virtual directory. If that is correct you dont need to get it from git.
Alternate way is to create a directory "main" and then project directory "mydjangoproject" inside it and a virtual environment "env".
C:\>mkdir main
C:\>cd main
C:\main>mkdir mydjangoproject
C:\main>virtualenv env
Now activate the virtual environment.
C:\main>env\Scripts\activate
Then install all the package in it. e.g
(env) C:\main>pip install django
I've already configured virtualenv in pycharm, when using the python manage.py command, this is error shown:
E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
Traceback (most recent call last):
File "manage.py", line 17, in <module>
"Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
How should I fix it, I've installed django.
I think the best way to use django is with virtualenv it's safe and you can install many apps in virtualenv which does not affect any outer space of the system
vitualenv uses the default version of python which is same as in your system
to install virtualenv
sudo pip install virtualenv
or for python3
sudo pip3 install virtualenv
and then in your dir
mkdir ~/newproject
cd ~/newproject
Now, create a virtual environment within the project directory by typing
virtualenv newenv
To install packages into the isolated environment, you must activate it by typing:
source newenv/bin/activate
now install here with
pip install django
You can verify the installation by typing:
django-admin --version
To leave your virtual environment, you need to issue the deactivate command from anywhere on the system:
deactivate
When you install Django on your computer all things go fine but when you install a Virtual environment it gets separated from all things. You will know it's importance when you will make a final project and deploy it to any cloud or hosting.
Just reinstall Django in the virtual environment and baam:
pip install Django
and then just run the command for testing:
python manage.py runsever
and you are all done.
You need to install Django, this error is giving because django is not installed.
pip install django
You need to use both commands:
pip install django and pip3 install django
that worked for me
Check that you have installed Django; by executing import django in python.
you mustn't see ModuleNotFoundError if everything's ok.
Check that you have installed virtualenv; by executing virtualenv --version.
you must see the version number if everything's ok.
Check that you have enabled virtualenv; there's got to be the name of your virtualenv in your command prompt starting line. enable it by
source bin/activate. also, remember to deactivate it every time your job is
finished with the virtualenv.
Check that your virtualenv includes django. a virtualenv by default
has no modules installed. you either have to install django in your
virtualenv (even if you have it in your machine already) or use
virtualenv --system-site-packages when creating a virtualenv to
include system site packages in the virtualenv.
Add django to your path. open python, import django, then run
django to see django's path. then add it to your ~/.bashrc (or
~/.zshrc if you're using zsh). more info in here
Install django-admin by running pip install django-admin
find your django parent dir path and add it to PYTHONPATH
In my case, my django parent dir path is /Library/Python/3.7/site-packages,add this line into ~/.bash_profile
export PYTHONPATH=/Library/Python/3.7/site-packages
else if you have PYTHONPATH already, just append it like this
export PYTHONPATH=${PYTHONPATH}:/Library/Python/3.7/site-packages
then
source ~/.bash_profile
I was having great difficulties with this but I have solved my issue. I am on Windows 10 using Vagrant ssh in my virtualenv environment, the box I have installed is ubuntu/xenial64, Django version 2.1, python==3.6.
When I was installing packages I was using pip3 but most importantly I was using sudo and the -H flag to install these packages. When I ran sudo pip3 freeze my packages would come up, but when I ran a plain pip3 freeze there would be no packages.
Then I tried the python3 manage.py startapp <YOUR APP NAME> and it did not work same error as you.
I finally thought to try sudo python3 manage.py startapp <YOUR APP NAME> it finally worked!
Hope this was help :)
I faced the same issue, and in my case it was because I had multiple python versions on my machine, in addition to the Anaconda ones.
In my case django didn't worked well with my anaconda python.
I knew that when I run import django on each python terminal for all versions I have.
As a summary here are the steps I made to get this solved:
Run the CMD as Admin
Create a project folder.
Create a new ENV for this new project INSIDE THE PROJECT Folder...
pip install virtualenv >> virtualenv new_env`
Activate it:
.\new_env\Scripts\activate`
After the env activation ⇒ Install Django:
python -m pip install Django
The python version you used here in step 5 will determine which python will to work with this installed Django.
If you are working on a machine where it doesn't have permissions to all the files and moreover you have two versions such as default 2.7 & latest 3.6 then while running the command use the python version with the command. If the latest python is installed with sudo then run the command with sudo.
exp:
sudo python3.6 manage.py runserver
after activating virtual env that error raises up on ubuntu.
and I solve this issue just by typing again :
pip3 install Django
inside the directory which is I want to create a new app.
You can use python3 to run file, if you don't want to use virtualenv.python3 manage.py runserver
To install python3 look at this page
Make sure you have Django installed by writing this command :
python -m django --version
if it's not installed you can install it by writing this command :
pip install django
I solved this problem in a completely different way.
Package installer = Conda (Miniconda)
List of available envs = base, djenv(Django environment created for keeping project related modules).
When I was using the command line to activate the djenv using conda activate djenv, the base environment was already activated. I did not notice that and when djenv was activated, (djenv) was being displayed at the beginning of the prompt on the command line. When i tired executing , python manage.py migrate, this happened.
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
I deactivated the current environment, i.e conda deactivate. This deactivated djenv. Then, i deactivated the base environment.
After that, I again activated djenv. And the command worked like a charm!!
If someone is facing a similar issue, I hope you should consider trying this as well. Maybe it helps.
Instead of creating a new virtual environment, you just have to access to your initially created virtual environment when you started the project.
You just have to do the following in your command line:
1)pipenv shell to access the backend virtual environment that you have initially created.
2) Then, python manage.py runserver
Let me know if it works for you or not.
To create a virtual environment for your project, open a new command prompt, navigate to the folder where you want to create your project and then enter the following:
py -m venv project-name
This will create a folder called ‘project-name’ if it does not already exist and setup the virtual environment. To activate the environment, run:
project-name\Scripts\activate.bat**
The virtual environment will be activated and you’ll see “(project-name)” next to the command prompt to designate that. Each time you start a new command prompt, you’ll need to activate the environment again.
Install Django
Django can be installed easily using pip within your virtual environment.
In the command prompt, ensure your virtual environment is active, and execute the following command:
py -m pip install Django
In case you have virtual env activated, django installed, django-admin --version prints the valid version - check if there is no circular import in the file you are executing.
I faced the same problem when I was doing it on windows 10. The problem could be that the path is not defined for manage.py in the environment variables. I did the following steps and it worked out for me!
Go to Start menu and search for manage.py.
Right click on it and select "copy full path".
Go to your "My Computer" or "This PC".
Right click and select "Properties".
Select Advanced settings.
Select "Environment Variables."
In the lower window, find "Path", click on it and click edit.
Finally, click on "Add New".
Paste the copied path with CTRL-V.
Click OK and then restart you CMD with Administrator privileges.
I really hope it works!
Looks like you have not activated your virtualenv when using the runserver command.
Windows: <virtualenv dir>\Scripts\activate.bat
Linux: source <virtualenv dir>\bin\activate
You should see (name of virtualenv) as a prefix to your current directory:
(virtualenv) E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
windows :
(virtualenv dir)\Scripts\activate # this step to activate virtualenv
you should be in the dir of (project name)
python manage.py runserver
you need to go to the root directory
and run the below command
source bin/activate
Once the above command is executed, you will be able to create custom apps
I also face the same problem in windows 10 with anaconda
For me anaconda3\Scripts>activate
it's working good. What you have to do you just need to go to anaconda home
AppData\Local\Continuum\anaconda3\Scripts
and you need to open a cmd prompt and type activate.
It will activate the venv for you.
if you don't want to deactivate or activate the already installed venv just ensure you have set the pythonpath set
set pythonpath=C:\software\venv\include;C:\software\venv\lib;C:\software\venv\scripts;C:\software\venv\tcl;C:\software\venv\Lib\site-packages;
and then execute
"%pythonpath%" %venvpath%Scripts\mytestsite\manage.py runserver "%ipaddress%":8000
The problem is related to this error: Execution Policy Change
Start virtualenv by running the following command:
Command Line
C: \ Users \ Name \ yourdjangofilesname > myvenv \ Scripts \ activate
NOTE: On Windows 10, you may receive an error by Windows PowerShell that the implementation of these scenarios is disabled on this system. In this case, open another Windows PowerShell with the "Run as Administrator" option. After that, try typing the following commands before starting your virtual environment:
C:\WINDOWS\system32> set-executionpolicy remotesigned
Execution Policy Change:
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the about_Execution_Policies help topic at http://go.microsoft.com/fwlink/?LinkID=135170.
Do you want to change the execution policy? [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "N"): A
After selection Y(es), close the Powershell admin window, and then go back to the Powershell Window(where you got the error) and run the command again.
> myenv\Scripts\activate and then python manage.py runserver 8085 ,
(8085 or any number if you want to change its default port to work on otherwise you dont need to point out anything. )
I had same problem, I installed all dependencies with root access :
In your case:
sudo pip install django
In my case, I had all dependencies in requirements.txt, So:
sudo pip3 install -r requirements.txt
Just sync your pipenv environment with:
pipenv sync
I had this problem with Django 3.
On manage.py detail the execute_from_command_line import.
You should have:
from django.core.management import execute_from_command_line
Instead of
from django import execute_from_command_line
I had the same problem and my solution was not posted here:
How I got the error
My error came whenever I was installation the requirements.txt file with pip (let's say from cloning a git repository).
Solution
I manually installed each of the modules in the requirements.txt + any other module needed for the installation of those modules (e.g: I got errors and some modules where missing to install other modules so I had to add them too).
If there is anyone who faced with the same problem when using virtual environment and running on MacOS, just try
sudo python manage.py startapp <project_name>
instead of
python manage.py startapp <project_name>
It will solve the problem suprisingly!
I had to install django using the virtual environment pip3 executable directly:
cd [virtual environment folder]/bin
sudo ./pip3 install django
If you already installed Django / configured virtualenv and you still having the error:
ImportError: Couldn't import Django. Are you sure it's installed and
available on your PYTHONPATH environment variable?
Try to run the command pipenv shell before start the server with py manage.py runserver
