Setup error for six package of django.utils

[Tareq Monwer]

I was following along the docs (https://django-base-site.readthedocs.io/en/latest/setup-and-usage.html) and I got this long error which is occured for django.utils.six while running migrate command.
Here is the error log:

django.core.cache.backends.base.InvalidCacheBackendError: Could not find backend 'redis_cache.RedisCache': cannot import name 'six' from 'django.utils' (/home/tareq/.local/share/virtualenvs/example-Y5_gWTrw/lib/python3.9/site-packages/django/utils/__init__.py)

Python: 3.9
OS: Manjaro
Am I missing any config or anything else?

Complete Error Log:

Hi @TareqMonwer,

Thank you for pointing this out. I started looking a little bit this morning, but I'm going to have to move on to some other things at the moment. That documentation is a little behind, especially now that I use Docker exclusively. I also checked out a fresh docker setup using the Quickstart method in the readme and it had the same issue. So this is something that will need to be fixed and I'll look into it soon.

@TareqMonwer,

I've pushed up several commits on master and also made a couple of tweaks to the manual install documentation.
