There are a couple of possibilities about why it might not work, but I think the first one to address is the virtualenv.
A virtualenv created on one computer is generally unlikely to work on another. It's not a proper self-contained system image, like a Docker container -- it has links going out to various system tools, and if those are in different places on PythonAnywhere to where they are on your local machine, it won't work. For that reason, it's not standard practice to include them in the repo -- instead, you include a requirements.txt
file that specifies what packages you need, then build a virtualenv outside the repo on each machine you're running on, using pip install -r requirements.txt
to install all of the appropriate stuff into it.
So the first thing to do is to rebuild the virtualenv on PythonAnywhere and then specify the new virtualenv on the "Web" tab.
That might not make it work right away, but it will get rid of one major cause of errors, and we'll be here to help if there are still problems :-)
