django:django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet

Question

I was stuck with the process when I wanted to deploy django project on server today. When I run python manage.py runserver on server, the terminal shows me this:

Traceback (most recent call last):

  File "manage.py", line 10, in <module>

    execute_from_command_line(sys.argv)

  File "/usr/lib/python2.7/site-packages/django/core/management/__init__.py", line 351, in execute_from_command_line

    utility.execute()

  File "/usr/lib/python2.7/site-packages/django/core/management/__init__.py", line 343, in execute

    self.fetch_command(subcommand).run_from_argv(self.argv)

    result = user_function(*args, **kwds)

  File "/usr/lib/python2.7/site-packages/django/core/management/__init__.py", line 72, in get_commands

    for app_config in reversed(list(apps.get_app_configs())):

    self.check_apps_ready()

  File "/usr/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.

The django version on the server is 1.8.5, and the local is 1.8.1. I doubt the version may cause this problem. But I also doubted the wsgi.py wasn't written properly, here's the wsgi.py:

import os

import sys

path = '/Users/Peterhon/Desktop/dict/'

if path not in sys.path:

    sys.path.append(path)

os.chdir(path)

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "dict.settings")

import django

django.setup()

from django.core.wsgi import get_wsgi_application

application = get_wsgi_application()

Here's the manage.py file:

#!/usr/bin/env python

import os

import sys

if __name__ == "__main__":

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "dict.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.arg)

When I run python manage.py check on server, the output is below:

#!/usr/bin/env python

import os

import sys

if __name__ == "__main__":

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "dict.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

Could anyone give me some tips? Thanks too much

This could well be an issue with your Django settings. For example, I just had specified in LOGGING a filename in a non-existent directory. As soon as I changed it to an existing directory, the issue was resolved.
