I installed pipenv using
$ pip3 install pipenv which gives me the error ImportError: cannot import name 'main'
in order to solve this error I followed these instruction sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall
now pip3 command is working on terminal.
now I install pipenv using pip3 install pipenv
it installed succesfully but when i tried to execute pipenv on termnal it gave me
pipenv: command not found at this point pip3 also gives ImportError: cannot import name 'main' error in order to solve this i followed these instruction
PYTHON_BIN_PATH="$(python3 -m site --user-base)/bin"
PATH="$PATH:$PYTHON_BIN_PATH"
at this, point pipenv is working but pip3 is not working .
How can I make both pip3 and pipenv work at the same time?
Also, it seems that I have messed up my pipenv setting now the virtual environment is created by default at /home/sysadmin
instead of the location i used to create virtual environment /home/sysadmin/Desktop/helloworld
The problem is due to overwriting the system-managed version of pip when installing pipenv. You performed the correct first step by getting your system-managed pip back in order:
sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall
Once that is done, it is important to note that pipenv will likely not be able to be installed at the global level due to the pip conflict. You can install pipenv at the user level:
pip install --user pipenv
This should install pipenv at a user-level in /home/username/.local so that it does not conflict with the global version of pip. In my case, that still did not work after running the '--user' switch, so I ran the longer 'fix what I screwed up' command once more to prep the environment:
sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall
and then did the following:
mkdir /home/username/.local ... if it doesn't already exist
export PYTHONUSERBASE=/home/username/.local
Make sure the export took (bit me once during this process):
echo $PYTHONUSERBASE
Then, I ran the pip install --user pipenv and all was well. I could then run pipenv from the CLI and it did not overwrite the global/system-managed pip module. Of course, this is specific to the user so you want to make sure you install pipenv this way while working as the user you wish to use pipenv.

I posted the question below, but none of the answers I was pointed to worked, though they look like they should.
I activated (again) the virtualenv. It still tells me that pip can't be found by apt when doing an 'apt install' command. But here is where I am now, and very confused.
I pointed my directory to "/home/.../q7root/bin/pip" and did an "ls". It shows a sub-directory with pip in it (or, I think, a link to it - I'm not the best at Unix). When I type "which pip" I get the path to this point ('q7root/pip'). bit if I just type "pip" at the CLI I get I get this error:
[![pip error][1]][1]
I have looked at my PATH, and this q7root/bin is the first place to look on the path. And, despite trying mightily with all the references people gave me, pip3 never gets installed.
But even pip is challenged. "which pip" points to this copy in the virtual environment site, but typing "pip" as a command tells me 'No module named pip.'
So pip seems to need more stuff installed (?), or there is some mess. Any advice?
Original Question:
At the suggestion of others working on what was a functional Django project, I upgraded to a more recent version of Ubuntu (18).
However, when I first try to run it it blows up at line 3 of the initial script module when asked to import django as a package.
I tried pip -r requirements.txt, but the system said pip was an unknown package. I dropped down and used apt to load pip onto my machine (sudo apt-get pip), then tried using pip itself (pip update pip) which failed.:
[![Pip load error message][2]][2]
I also tried pip install django, and got this:
[![django not found][3]][3]
I would have thought an OS upgrade would not require re-installing all currently installed packages (seems like a no-brainer to do the work of installing everything that had been installed). But right now I am terribly stuck...obviously, having 'pip' let's you (at least) have a basic CLI tool.
Any advice?

It depends on the version of python.
Python 3
sudo apt update
sudo apt install python3-pip
Python 2
sudo apt update
sudo apt install python-pip
How to Install Pip on Ubuntu 18.04
Start with a fresh Ubuntu install. I think you've run too many commands for your current setup to be reproduceable.
Install python3 and python3-venv.
sudo apt update
sudo apt install python3 python3-venv
Use the venv module to create the virtual env.
python3 -m venv myenv
source myenv/bin/activate
You now have access to pip in the venv.
It's OK to upgrade pip in the virtual env, I suggest you don't ever upgrade the system pip otherwise you might hit issues like this.
(myenv) python -m pip --version
(myenv) python -m pip install --upgrade pip
Now you can use pip to install your requirements in the virtual env.
(myenv) python -m pip install -r requirements.txt
In the above commands I've used python -m pip instead of pip. This is the recommended way, as it ensures that you are using the version of pip that matches python.
In the end, this was a state of deep computer confusion. I was already disk-limited so I bought a new computer, and this error did not recur with the same code being used.
I'm trying to do: pip install -r requirements.txt on an AWS server. I recently pulled a git commit.
I get this error:
Command 'pip' not found, but can be installed with:
sudo apt install python-pip
So I tried entering:
sudo apt install python-pip install -r requirements.txt
and then
sudo apt install python-pip -r requirements.txt
But both attempts gave me this error:
E: Command line option 'r' [from -r] is not understood in combination with the other options.
What is the correct command to install this? Thank you.
You are mixing multiple commands.
apt ; It is Debian's package manager. It has nothing to do with python packages. You install pip through apt. There are also other ways of doing it.
pip : As understood it is python package manager. You can install dependencies for your project by listing them in requirements.txt.
The correct way would be :
sudo apt install python-pip
#install from a file requirements.txt:
sudo pip install -r requirements.txt
#install as a user :
pip install -U -r requirements.txt
My pip package is corrupted. I need to install boto3 using apt-get but I get the following error when I do apt-get install python-boto3:
E: Package 'python-boto3' has no installation candidate
Can someone please help me find a alternate way or some way to make apt-get work?
Thanks in advance!
You can't use apt-get to install python packages. In order to install a python package, pip resolves dependencies and build wheels. apt-get doesn't have the functionality to do the same.
You can purge the previous installation of pip:
sudo apt-get remove --purge python-pip
then install a new one:
curl https://bootstrap.pypa.io/get-pip.py | sudo python
finally, try installing boto3:
sudo pip install boto3
I've just learned how to use virtualenv and I installed Django 1.4.5. I'm assuming that the virtualenv created a clean slate for me to work on so with the Django 1.4.5 installed, I copied all my previous files into the virtualenv environment.
I tried to run the server but I get an error saying "no module named MySQLdb". I think this means that I forgot to install MySQL-python. I tried to install it via
pip install MySQL-python
But I get this error

Not quite sure how to go about fixing this problem =/ any help much appreciated!
I recently had exactly this issue (just not in relation to Django). In my case I am developing on Ubuntu 12.04 using the default pip and distribute versions, which are basically a little out of date for MySQL-python.
Because you are working in an isolated virtualenv, you can safely follow the suggested instruction without affecting your Python installation.
So you can...
workon your_virtualenv #activate your virtualenv, you do use virtualenvwrapper, right?
easy_install -U distribute #update distribute on your virtualenv
pip install MySQL-python #install your package
If for some reason upgrading distribute is not an option, you could try installing an older version of MySQL-python as follows (you'd have to check this version is compatible with your version of Django):
pip install MySQL-python==x.y.z #where x.y.z is the version you want
Spent an hour looking through stackoverflow. Evntually found answer in the other question. This is what saved me:
sudo apt-get install libmysqlclient-dev
mysql_config goes with the package.
When doing in a virtualenv :
pip install MySQL-python
I got
EnvironmentError: mysql_config not found
To install mysql_config, as Artem Fedosov said, first install
sudo apt-get install libmysqlclient-dev
then everything works fine in virtualenv
MySQL driver for Python (mysql-python) needs libmysqlclient-dev. You can get it with:
sudo apt-get update
sudo apt-get install libmysqlclient-dev
If python-dev is not installed, you may have to install it too:
sudo apt-get install python-dev
Now you can install MySQL driver:
pip install mysql-python
Here is a more detailed documentation for MySQL in Django:
http://codex.themedelta.com/how-to-install-django-with-mysql-in-a-virtualenv-on-linux/
I had to do this:
pip install mysql-python
inside the virtualenv
The commands are always run in ubuntu:
easy_install -U distribute
later
sudo apt-get install libmysqlclient-dev
and finally
pip install MySQL-python
The suggested solutions didn't work out for me, because I still got compilation errors after running
`$ sudo apt-get install libmysqlclient-dev`
so I had to run
apt-get install python-dev
Then everything worked fine for me with
apt-get install python-dev
Try this:
Version Python 2.7
MySQL-python package, you should use either MySQL_python‑1.2.5‑cp27‑none‑win32.whl or
MySQL_python‑1.2.5‑cp27‑none‑win_amd64.whl depending on whether you have installed 32-bit or 64-bit Python.
pip install MySQL_python‑1.2.5‑cp27‑none‑win32.whl
if you are using mysqlclient package, then use
mysqlclient‑1.4.6‑cp27‑cp27m‑win32.whl or
mysqlclient‑1.4.6‑cp27‑cp27m‑win_amd64.whl
pip install mysqlclient‑1.4.6‑cp27‑cp27m‑win32.whl

I am trying to get the django_auth_module working but I don't think I managed to install it properly.
I downloaded the package and ran setup.py install.
Then in my settings.py file I tried to import the module ldap and it gave me the following error :
ImportError: no module named ldap
I am working on a CentOS 6 server.
Maybe it has to do with where I should install the module? The folder is in the directory just above my site folder, but maybe that's wrong...
RESOLVED :
Ok, I just needed to install the module python-ldap... problem solved!
Install missing module
Hint: To install python-ldap with pip on Ubuntu, some libraries are needed.
Use the apt-get commands to install them.
Python 2
sudo apt-get install python-dev libldap2-dev libsasl2-dev libssl-dev
sudo pip install python-ldap
Python 3
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
sudo pip3 install pyldap
Try the below command to install for Python3.
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
sudo pip3 install pyldap
