I just learned that Pipenv is no longer an official project.
I request we remove references to it from the page
https://packaging.python.org/guides/tool-recommendations/
This issue is a part of work that reverses #437 and clarifies that pipenv is not an official project.

It can't even go about the simple process of:

1. pipenv install
2. pipenv uninstall --all-dev

without giving an error.
See
pypa/pipenv#3469
to track this issue.
