AttributeError: 'NoneType' object has no attribute 'pythons' when creating new pipfile

See original GitHub issue

Issue description

I tried to run pipenv install --verbose and it failed.

Expected result

I expected a virtualenv to be set up, a pipfile to be created, and no errors to pop up.

Actual result (ran with --verbose)

Had a similar issue and the problem for me was that macOS had created a .DS_Store file in the versions folder for pyenv, which Pipfile was choking on. A quick workaround is to simply remove that file, so

rm /Users/YOUR_USER_NAME/.pyenv/versions/.DS_Store

Sorry I have one more update: I changed the pipenv command and managed to get things working again! What I was doing before: pyenv global 3.7.2 pipenv install = Fail pyenv global 3.7.2 pipenv install --python=~/.pyenv/versions/3.7.2/bin/python = Fail pyenv global 3.7.2 pipenv install --python=/Users/Will/.pyenv/versions/3.7.2/bin/python = Success! pythonfinder does not appear to like the tilde path perhaps?
