Hi, this project's Pipfile specifies Python 3.6, which I don't have installed locally, so I thought I'd bump it to 3.7 for my project. (Edit: this may or may not be actually related; maybe if someone has 3.6 installed they can check).
The Pipfile also specifies django = "*" (so Django 3.0 got installed) and whitenoise = "==4.0". However, whitenoise 4 is apparently not compatible with Django 3, because it tries to import from django.utils.six, which I guess has gone away in Django 3 (before, after). This resulted in errors like:

Whitenoise 5 is out, so this seemed to fix the problem for my purposes:

Or alternatively you could specify Django 2.2 if you don't want to bump the Python and the Django versions.
