Model class address.models.Country doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS

[nimame]

I am using django-address 0.2.5 in my django 3.1 app. I am trying to run some parts of the app from the command line using:

from django.conf import settings
import os

settings.configure(DEBUG=True)
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'web.settings')
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

When I try to import my models, I get the following error:

>>> import app.models
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/django/app/models.py", line 18, in <module>
    from address.models import AddressField
  File "/usr/local/lib/python3.8/site-packages/address/models.py", line 168, in <module>
    class Country(models.Model):
  File "/usr/local/lib/python3.8/site-packages/django/db/models/base.py", line 113, in __new__
    raise RuntimeError(
RuntimeError: Model class address.models.Country doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

Another curious observation: My IDE (PyCharm) shows the following warning when importing address: "Package containing module 'address' is not listed in project requirements", even if it is listed in the requirements.txt.

Can anyone help?

Hello! @nimame, thanks for trying django-address.

Sorry to hear about the trouble getting the library to work.

One quick thing that comes to mind is, have you added 'address' under the INSTALLED_APPS section of your settings.py?

Regarding PyCharm, (I also use PyCharm for django and like it a lot), I wonder if this error could again have something to do with your settings. 

Have you tried opening the sample example_site that comes with the library?
