I am converting a Django website from Python 2 to Python 3. To do this, I ran 2to3 on the whole project. Now, upon running the server (which works fine in Python 2). Now, there appears to be an error django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. that seems to originate with an issue loading the django_comments app. It is not clear to me whether this is related to a templates/models issue or something else. Python3 was installed in the virtual environment for this project.

(env) user:project user$ python3 manage.py check

I have also ensured that DJANGO_SETTINGS_MODULE is configured in manage.py.

maybe you can do like this in manage.py：

import os
import django
import sys

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mis.settings")
django.setup()

from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)

  • Thank you but no luck. The same error is thrown except the traceback starts at django.setup() as below: `Traceback (most recent call last): File "manage.py", line 9, in django.setup() File "~/src/app/env/lib/python3.7/site-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) ...` – woefipuasd Oct 29 '19 at 03:14

I just found an answer pythonanywhere, it means that you shouldn't need to call django.setup().In addition, you can try to disable your apps in INSTALLED_APPS one by one so that can identify where the problems from.Don't forget to restore the code in manage.py at first!

  • Thank you. This is what I am trying now. By 'restore the code in manage.py' I presume you mean revert any changes I made (such as adding django.setup()? – woefipuasd Oct 29 '19 at 19:32
