Django 1.7 upgrade error: AppRegistryNotReady: Apps aren't loaded yet

Question

I am trying to upgrade a project from Django 1.6 to 1.7. I get the following error:

[Thu Oct 09 14:16:41 2014] [error] [client 95.79.172.156] mod_wsgi (pid=1         


        

Answer 1

INSTALLED_APPS Had an missing comma in the array, that caused the error for me.

Answer 2

I had a similar (the same?) isssue when upgrading to Django 1.7. In may case, it was enough to update the wsgi file: replace

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

with

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Answer 3

It could be any reason. In my case, I updated my python version outside of my virtual environment, but my virtualenv was still the old version, that makes the error. I deleted the env and build it again using the newer version, and it worked.

Answer 4

Just reinstall Django using the command line, not in Pycharm helped to me.

Answer 5

In my case SEcret_key was commented by mistake in settings.py

Answer 6

In my case, I forgot to add one of my sub-applications inside INSTALLED_APPS.

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'basketball',
    'basketball.area',
    'basketball.game',
    'basketball.player',
]
