PyCharm Django test runner can't see django.sites (Runtime Error)
Question: When I run `manage.py test` everything is working normally, but if run test
with PyCharm Django Tests it gives me following error:

    
    
    Error
    Traceback (most recent call last):

**Yes, I've enabled** `'django.contrib.sites'` **in INSTALLED_APPS and SITE_ID
is set.**

Any ideas?


Answer: I created local virtualenv and install same requirements — tests work fine
with it.

Thanks, everybody for comments.
