I have a Django application, which very suddenly started giving me an error. I made a code change, restarted the application, and now I can't get rid of this error. I really don't think that I did anything else in between the two runs.
The error is ImportError: "No module named unittest" I don't know if it thinks it should be running a unit test or if this just happens to be the first thing to fail.
I have tried running it both from Eclipse and from the CMD line with manage.py runserver. Same error. (This is an update. previously I had only tried from Eclipse.) A brand-new project made in Eclipse has the same error.
This happens with any web application (using runserver), so it's not my code. I also reverted back to older code that worked fine before.
I have tried restarting my computer.
I am able to run "regular'(not a web application) python programs from the cmd line. So it does find Python.
I honestly have no idea what to do at this point, except to reinstall Python, which I'd like to avoid. Anyone?
NEW Stack trace (Update: previous was from Eclipse and just showed pydev errors. Run from cmd line it shows more python.)
