Error running "Django-polls" package in my project

[Temidayo]

In line with instruction in this tutorial, ​https://docs.djangoproject.com/en/4.0/intro/reusable-apps/, I removed my polls app from the polls project, then built the polls app package.

After several tries, I was able to successfully install the polls package. Here is quote from my command line

PS C:\Users\MY PC\desktop\django_exp\src\django_novice> pip install --user django-polls/dist/django-polls-0.1.tar.gz

DEPRECATION: Source distribution is being reinstalled despite an installed package having the same name and version as the installed package. pip 21.1 will remove support for this functionality. A possible replacement is use --force-reinstall. You can find discussion regarding this at https://github.com/pypa/pip/issues/8711.

Now, after this installation, I tried the `python manage.py runserver` command to bring back up the development server, but unluckily for me, I got an error.

There was a ModuleNotFoundError: No module named 'polls'

Can anyone help with advise of how to solve this?
