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

Created on 12 Jan 2019 · 20Comments · Source: pypa/pipenv

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`)

Steps to replicate

Provide the steps to replicate (which usually at least includes the commands and the Pipfile).

`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

Looks like a bug in pythonfinders.

Hi, thanks for the awesome tool. Looks like I ran into the same problem. Is there an earlier version pf pipenv that can create new packages on Unix systems?

I am encountering the same issue here I think, using pyenv 1.2.9 (via homebrew) and pipenv 2018.11.26 (via homebrew) on OSX 10.14.3. I have a difference in that I was using already setup venv (using pyenv).

`>$ pipenv --support
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

Interestingly I spot that it is looking at a python with (invalid) name "venv372" which is not what I named my venv using pyenv... although version 3.7.2 would be correct.

After a little more playing, I have found that it doesn't work either when using pipenv install to creat the venv, e.g.:

`>$ pipenv install

What strikes me as strange about this, and also my previous error posted above, is that xxxx-xxxxxx-3.7.2 is not a python version refers to venv which I created previously (using pyenv), but had deleted fully from ~/.pyenv/versions/... (both symlink and actual venv folder) before running the pipenv install command. Similarly above in my first post, venv372 was the first name I gave to my first venv which I was trying this out with... It seems like somehow this is sticking around even after I delete the venv. In the second instance, even when pipenv creates it's own venv it seems to have found an (old and already deleted) name of a pyenv-created venv...

Sorry if that sounds confusing.

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?

@WillAyd Oh man, I _did_ have a .DS_Store file in ~/.pyenv/versions/, and I was hoping that was the issue, but removing it didn't work for me. After removing it, here's my pipenv --three output:

This output looks different from the original issue, but there sure seems to be something fishy going on with creating virtualenvs with pipenv. It's been busted for me since last year :(

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.

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. :smiley:

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

I ran into the same issue with the pythonfinder acting up, none of this seemed to work.

I found a workaround that helped me:

Remove the pipenv executable from ~/.local/bin/ (or wherever it's located)
Use pyenv to download a fresh python 3.6.5 and setting it as my global python version
Installing pipenv in that and rebuilding the virtual-environment from the Pipfile

I'm still not sure what was the problem but this helped me get the work done

jimc404 on 30 May 2019

Further explanation of @dammitjim 's solution. For me, the issue was due to a dead symlink in my ~/.pyenv/versions folder. Earlier, I deleted the symlink target but forgot to remove the symlink itself. Removing the symlink fixed it.

The culprit symlink:

my-test-venv -> ~/.pyenv/versions/3.6.0/envs/my-test-venv

umairishaq on 25 Jul 2019

I think the problem started for me when I added the virtualenv plugin to pyenv. It created symlinks in the versions folder.

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

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.

I had the same issue on linux.
it was found that removing the eval "$(pyenv init -)" directive from my ~.bashrc solved it

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 It seems to resolve the issue for me. Thanks for a lot for your work, looks like I can finally move away from those requirements.txt files. (Checked on Ubuntu 16,18 and Debian 9, using pyenv on all of them)

On a related note when is the next release (or just the tentative dates)?

@techalchemy I seem to have an issue with namespace packages

I fixed the problem with the following:

brew uninstall pipenv
brew uninstall pyenv
sudo rm -rf .pyenv               # sudo is required somehow

brew install pipenv
pipenv install                      # works!

My errors were:

$ pipenv install
Warning: the environment variable LANG is not set!
We recommend setting this in ~/.profile (or equivalent) for proper expected behavior.
