Django, ModuleNotFoundError: No module named 'django_pg' - django

Question

Can someone provide more details on setting up and utilizing django_pg. I would like to use the array functionality.
By following the setup of two simple steps from here:
https://django-pgfields.readthedocs.io/en/latest/usage.html
Results in this error:

Answer 1

It looks like you forgot to do pip install django-pgfields to install it.
However, you probably shouldn’t be using this package. It hasn’t had any updates for years, so won’t support modern versions of Django.
Since Django 1.8,
Django comes with django.contrib.postgres, which might provide the Postgres functionality that you require.
