Aktualizacja Django 1.8 do 1.9: django.core.exceptions.AppRegistryNotReady: Aplikacje nie są jeszcze załadowane

Question

Mam projekt aktualnie pracujący nad Django 1.8. Od 1.9 właśnie wydany, myślałem, że będę aktualizować poprzez pip install django==1.9. Jednak, gdy uruchomiony python manage.py test -v 3, otrzymuję ten błąd:

Traceback (most recent call last): 
    File "manage.py", line 11, in <module> 
    execute_from_command_line(sys.argv) 
    File "/home/user/Envs/intranet/lib/python2.7/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line

    File "/home/user/Envs/intranet/lib/python2.7/site-packages/django/apps/registry.py", line 124, in check_apps_ready 
    raise AppRegistryNotReady("Apps aren't loaded yet.") 
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. 

Jestem świadomy, że INSTALLED_APPS zmieniona z krotka do listy.

Coś jeszcze, co mogłem przegapić?

próby uaktualnienia Django rewersji, dziś ukazał 1.10 version z:

Django 1.9 compatibility (@etianen).

wiadomości z grup dyskusyjnych https://groups.google.com/forum/#!topic/django-reversion/3AQipnbKaUI

The latest release of django-reversion (1.10.0) is now available on GitHub and PyPi. This release adds compatibility with Django 1.9.

Important: This release contains breaking changes. Please review the release notes on GitHub before installing.

These breaking changes were unfortunately required in order to support Django 1.9. Happily, all you'll need to do is modify your reversion import locations, and everything will continue to work.

Happy coding!
