    django_redis is trying to import six from django.utils

    File “/home/yangcoco/.virtualenvs/Django_czbk/lib/python3.6/site-packages/django_redis/util.py”, line 8, in
    from django.utils import six

    However, six has been removed from django. Check Django 3.0 release notes here

    Either switch to bleeding edge django_redis or to Django 2.2 if you need to use this specific version of django_redis

    You could try installing the bleeding edge version of django-redis to fix the issue.

    This would enable you to use Django 3 that comes with features that can change how you’ll develop your app.

    To do so, just install the package directly from GitHub, if you’re using Pipenv like I am, just issue the following command:

    pipenv install git+https://github.com/niwinz/django-redis.git@master#egg=django-redis

    If you still want to stick to Django 2.X just edit the Django entry in your Pipfile to:

    django = "==2.*"

    Or issue the following command:

    pipenv install "django==2.*"
