On Django version 4.0, when testing,

I've needed to update the imports on cluster.py to include

Django

from django import core, db
from django.apps.registry import apps

try:
apps.check_apps_ready()
except core.exceptions.AppRegistryNotReady:
import django

django.setup()

from django.conf import settings
from django.utils import timezone
from django.utils.translation import gettext_lazy as _

This ensures all apps are imported before the cluster starts and tasks.py are imported correctly.

I did all the installation instructions but get this error:

Unknown command: 'mscluster'. Did you mean qcluster?
