PyCharm throws "AttributeError: 'module' object has no attribute" when running tests for no reason

Question

So, I have a Django-REST Framework project and one day it simply ceased being able to run the tests within PyCharm.

From the command line I can run them both using paver or the manage.py directly.

There was a time when that would happen when we didn't import the class' superclass at the top of the file, but that's not the case.

We have a virtualenv set locally and run the server from a vagrant box. I assured the virtual environment is loaded and that the project's Interpreter is using the afore mentioned virtual env.

No clue on what's the matter.

Answer 1

I had the same problem but my solution was different.

When I tried to run a test from PyCharm, the target path looked like this:

• tests.apps.an_app.models.a_model.ATestCase

But since ATest was a class inside a_model.py, the targ path should actually be:

• tests.apps.an_app.models.a_model:ATestCase

Changing the target in the test configuration worked.

Answer 2

Given all the others paths were already covered:

• Import order
• Virtual Env created
• Project's Interpreter using the Virtual Env

The only thing that occurred to me was do run the following command within the vurtal env:

pip install -r requirements.txt

And it worked! In the end, someone had updated the requirements which weren't being met by my current virtual env. Screwing up with the paths/imports within PyCharm.
