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

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`)

`pipenv install --verbose` on macOS with pyenv installed.

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?

In case anybody winds up here from Google, I had this issue and the reason was a symlink in my .pyenv/versions folder. Upon removal of the symlink all was well.

It appears that plonking anything other than exactly what pyenv expects in the versions dir causes unexpected behavior. 😃

I ran into this even though my ~/.pyenv/versions folder looked just fine at first glance. Following the suggestions in this thread I dug a bit more and found that one of my python versions was missing a bin/ folder inside it, probably a botched install; removing that folder/install fixed my pipenv issues.

p.s. the way I figured out something was wrong with that particular version (it wasn’t the version I was trying to use btw) was that the 3.6.3 folder was slightly smaller than all the other ones, and upon inspection the corruption became obvious

In my case, I had a zip file in the .pyenv/versions/ directory (long story: my compiler is broken on one machine, so I have to copy new python versions across).

Removing the zip file(s) means it works.

to those struggling with this issue – can you confirm whether it is resolved using the prelease version? You can install the prerelease via pip install --upgrade --pre pipenv

techalchemy on Apr 29, 2020

The vendored pythonfinder package has a bug in it: https://github.com/sarugaku/pythonfinder/issues/79

I got things working by patching pythonfinder. I’ve written more in that ticket, including what I did to workaround the bug. It might not work for all situations though.

getting this error below when running:

pipenv --python 3.7.4

where python 3.7.4 is the global python set so by pyenv

from the above it sounds like this should either have already been resolved, or is due to symlinks in the .pyenv/versions/X.X.X/bin/ directory

I re-installed everything, i.e. pyenv, virtualenv, and pipenv today and the issue is still coming up. So it’s not due to an older version.

got it to work by setting the python version explicitly by path:

pipenv --python ~/.pyenv/versions/3.7.4/bin/python3.7
