Pipenv: "pipenv --python X.Y" fails with a traceback if pyenv has debug versions installed

Created on 9 Oct 2018 · 14Comments · Source: pypa/pipenv

Be sure to check the existing issues (both open and closed!), and make sure you are running the latest version of Pipenv.

Check the diagnose documentation for common issues before posting! We may close your issue if it is very similar to one of them. Please be considerate, or be on your way.

Make sure to mention your debugging experience if the documented solution failed.

Issue description

pipenv --python X.Y command checks pyenv's version list and does not like the debug builds (whose versions look like X.Y.Z-debug) failing with a traceback.

Expected result

I would expect pipenv to ignore unsupported versions silently (and with one warning per incompatible version in verbose mode), and proceed with installing what it wants.

Actual result

pyenv versions

immerrr@mmrcomp:~/pipenv-temp$ pyenv versions
* system (set by /home/immerrr/src/pyenv/version)
  3.6.4
  3.6.6
  3.6.6-debug
  3.7.0

pipenv --python 3.6.4 (traceback)

Steps to replicate

$ mkdir pipenv-temp; cd pipenv-temp
$ pyenv install 3.6.4
$ pyenv install 3.6.6 --debug
$ pipenv --python 3.6.4

pipenv --support is not much of a help here, because it tries to report a list of existing python versions.

I will leave it here just in case, it helps to debug.

This could be a bug in pythonfinder.

finder = Finder(system=False, global_search=True)

yeah this is definitely a bug in pythonfinder, I thought we fixed this actually...

techalchemy on 9 Oct 2018

can you file against pythonfinder with these logs so we can track it over there? thanks

techalchemy on 9 Oct 2018

@techalchemy sure: https://github.com/sarugaku/pythonfinder/issues/12

immerrr on 9 Oct 2018

I've added a PR that implements a flag for pythonfinder to ignore unsupported python versions and thus silence the errors. An extra step on pipenv side of things is probably to ensure that the warning for unsupported versions is shown with --verbose flag.

immerrr on 12 Oct 2018

@techalchemy whoops, i think i have misplaced the word "fix" in the description to https://github.com/sarugaku/pythonfinder/pull/14, this should probably be reopened until there's a PR that enables that flag

This bug occurs at 2018.10.9, too.

This bug in fact only occurs in 2018.10.9 as that is the only version with pythonfinder in it. It will be fixed in the follow up release in 20 mins

techalchemy on 13 Oct 2018

I still get the error with pipenv==2018.10.13 and pyenv.

andreif on 19 Oct 2018

Managed to get it working with the older versions:

pip install pip==18.0
pip install pipenv==2018.7.1

I've managed it with brew on macOS:

brew switch pipenv 2018.7.1
pipenv --python 3.6.4

and then back as version 2018.7.1 has its own bugs:

brew switch pipenv 2018.10.13

I had the same error with ubuntu 18.10: its python 2.7 in /usr/bin/python reports itself as 2.7.15+ and the + doesn't amuse pythonfinder.

(With the info here I added a quick .rstrip('+') into the vendored pythonfinder, so I'm ok. And I see the fix will be included in the november bugfix release. So I mostly mentioned it to help people googling for the ubuntu 18.10 problem.)
