Django 1.8 to 1.9アップグレード：django.core.exceptions.AppRegistryNotReady：アプリケーションはまだロードされていません

Question

私は現在Django 1.8で作業中のプロジェクトを持っています。 1.9がリリースされて以来、私はpip install django==1.9で更新すると思った。 python manage.py test -v 3を実行している場合しかし、私はこのエラーを取得する：

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/contrib/contenttypes/models.py", line 159, in <module> 
    class ContentType(models.Model): 
    File "/home/user/Envs/intranet/lib/python2.7/site-packages/django/db/models/base.py", line 94, in __new__

    self.check_apps_ready() 
    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. 

私はINSTALLED_APPSリストにタプルから変更されたことを認識しています。

他にも私が見逃したことはありますか？

今日はと1.10 versionにリリースされた、ジャンゴ・復帰をアップグレードしてください：あなたが更新する必要のあるものを見るために `manage.py check`を実行することができますディスカッショングループ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!
