I have tried to create envelope on my linux pop os system using miniconda. When I activate it, I can install packages using pip, but when I run my django instance it doesn't find the modules.
If I type which python is shows the miniconda path correctly. I can look in the site-packages folder and see the packages installed.
I've tried installing django-anymail and corsheaders and they are both not being found. It does find my locally installed apps.
If I use the command line and open python and then import, it does not recognize my modules installed in the virtual envelope either. I thought it was a problem with conda, so I also created an envelope using python's native method: python3 -m venv
I have the same problem with it finding pip install site-packages.
Is there a command I can run to show all available packages?
I hadn't realized I had aliased my python. Now it is working.

I've been following a Django tutorial and initially created virtualenv and a requirements file in it. Project was halfway and in working state. Today I activated virtualenv successfully and tried python manage.py runserver to get error
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 realized it's not finding Django and just to be sure checked my requirements.txt file (which confirmed right Django version). Tried to reinstall it from the file using pip3 install -r requirements.txt (tried using just pip too) to get another error --
ModuleNotFoundError: No module named 'pip'
It seems the environment is unable to find any of the modules. I tried to reinstall pip also just to be sure, but then it couldn't find apt-get command.
OS: Mac OSX El Capitan 10.11.6
Python: 3.6.2
Django: 1.10.3 (in requirements file)
Try running python -m ensurepip (or python3 -m ensurepip) to see if pip is already installed:
In most cases, end users of Python shouldn’t need to invoke this module directly (as pip should be bootstrapped by default), but it may be needed if installing pip was skipped when installing Python (or when creating a virtual environment) or after explicitly uninstalling pip.
Currently, I am facing difficulty installing difflib module in python 2.7 version in windows 10 system.
I want it to perform some text analytics analysis
tried using
apt-get install npm
npm install difflib
and
pip.exe install difflib
Solution for me was to save the difflib.py in the location where your .py file resides and then import it in your file.
install using pip should be a great idea, You can refer to the module related details here:
https://docs.python.org/2.7/library/difflib.html
If you face an issue installing it using pip, then the next way is to get the difflib.py from any working machine and keep it in the project directory itself, so that just importing the module itself will work.
This is the codebase reference from svn of python itself:
https://svn.python.org/projects/python/trunk/Lib/difflib.py
I am trying to install django-dash to run one of the dashboard examples and see what it's like.
I am on Windows running Python 2.7 and Django 1.6.5. I know the usual approach is to download pip then install the package using pip. However, I am on a work computer with no administrative rights so I can't access my Internet Option Settings to find my proxy URL to follow the instructions below:
Proxy problems
If you work in an office, you might be behind a HTTP proxy. If so, set the environment variables http_proxy and https_proxy. Most Python applications (and other free software) respect these. Example syntax:
http://proxy_url:port
http://username:password#proxy_url:port
I had the same issue when trying to install Django but was able to get it to work by moving the django directory under Python27/Lib/site-packages. Is there something similar I can do with django-dash?
I also tried downloading the sources and running python setup.py install. I received the following error:
File "setup.py", line 3, in <module> from setuptools import setup, find_packages ImportError: No module named setuptools
Link to django-dash: http://django-dash.readthedocs.org/en/latest/
Yes, you can probably get the sources from The Python Package Index
Once you have them, uncompress the files and install them manually (this will depend on you OS).
On Linux systems:
python setup.py build
python setup.py install
Here's the full reference
EDIT : Note that when manually installing those packages, you must also install any missing dependencies, eg. setuptools in your case
I recently installed ipython, and along with it, anaconda. However, anaconda changed my sys.path directories, and some of the packages I was using before stopped working. Even after uninstalling anaconda using pip, it seems that those directories remained. How do I change them back? When I enter the python shell, I do and see the following:
Anaconda installs its own Python. When you run that Python, it uses the Anaconda Python libraries. The Anaconda installer put a line in your .profile that makes it first in the PATH, so that when you type python, it loads the Anaconda Python.
If you want to use the Python packages that you had installed into another Python with Anaconda, you will need to install them, using conda (or pip if they are not available via conda)
Anaconda is a separate python environment and as such doesn't have access to anything you installed in the base python environment. Depending on the project is usually a good idea to have separate environments using virtualenv or a similar tool. You can also do this using Anconda as described below.
Create a virtual environment for your project
conda create -n yourenvname python=x.x anaconda
Activate your virtual environment
source activate yourenvname
Install additional Python packages to a virtual environment.
conda install -n yourenvname [package]

I installed python 2.6 alongside my mac's 2.5.2 version. As soon as I did, python2.6 manage.py runserver failed because it couldn't find django.core.management.
From a shell, import django returns importerror: No module named django.
Why?
Did you reinstall Django?
This happens when I install side by side versions of Python on Gentoo. Whenever I install a new version, I have to either reinstall the new ones or make a symlink to the old site-packages.
Because each installation of Python uses its own directory to store libraries. On a Mac, they are in /Library/Python/2.x/site-packages/. Presumably you originally installed Django in the 2.5 directory, but it isn't yet in the 2.6 one. You can symlink it there if you want to, or reinstall it using the new version.
Add site-packages to PYTHONPATH:
export PYTHONPATH="/home/jerome/bin/django-1.1/lib/python2.6/site-packages:$PYTHONPATH"
Worked on Ubuntu, with a python/django virtual environment using virtualenv and pip.

I use Bitnami's Django installer, and this happened for me when I wasn't in their custom shell, which I believe sets related python path environment variables. I ran ./use_djangostack in the root of the Bitnami package and then was successful running the server again.
