Aggiornamento da 1.8 a 1.9 da Django: django.core.exceptions.AppRegistryNotReady: le app non sono ancora state caricate

Question

Ho un progetto che attualmente funziona su Django 1.8. Dalla versione 1.9 appena rilasciata, ho pensato di aggiornare tramite pip install django==1.9. Tuttavia, durante l'esecuzione python manage.py test -v 3, ottengo questo errore:

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. 

Sono consapevole che INSTALLED_APPS cambiato da una tupla a un elenco.

Qualcos'altro che potrei aver perso?

tenta di aggiornare django-reversione, oggi è stato rilasciato 1.10 version con:

Django 1.9 compatibility (@etianen).

messaggio da gruppi di discussione 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!
