Тестировщик PyCharm Django не видит django.sites (Ошибка времени выполнения)

Question

Когда я бегу manage.py test все работает нормально, но если запустить тест с PyCharm Django Tests, он выдаст мне следующую ошибку:

Error
Traceback (most recent call last):
  File "/usr/lib/python3.4/unittest/case.py", line 58, in testPartExecutor

RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

Да я включил 'django.contrib.sites' в INSTALLED_APPS и SITE_ID установлен.

Есть идеи?

Я создал локальный virtualenv и установил те же требования - тесты работают нормально.

Спасибо всем за комментарии.
