Nixpkgs: Pipenv fails to create virtualenv outside of `nix-shell`

Issue description

Running pipenv install in a project that doesn't already have a venv fails with the following message:

 $ pipenv install

This happens when Pipenv is installed with nix-env -i pipenv or by adding it to systemPackages, but not when ran in a nix-shell -p pipenv. It also does not happen if the venv already exists.

Running pipenv --rm && pipenv install triggers the error again (if ran outside of nix-shell).

Steps to reproduce

nix-env -i pipenv
cd $(mktemp -d)
pipenv install

Will this fix be included in the 19.03 stable channel?

Even weirder, this also happens when ran using nix run nixpkgs.pipenv.

teozkr on 9 Oct 2018

Seems like the culprit is that $PYTHONPATH is set by nix-shell, but not the others. Copying the contents of that env variable makes it work in both nix run and the user profile.

teozkr on 9 Oct 2018

I have this problem too. Thanks @teozkr for the work-around :-)

stig on 15 Oct 2018

I have the same issue, and tried to dig a little bit into it.

IMO the problem is, that pipenv executes "python -m 'virtualenv'" as a subprocess (in core.py), so the virtualenvwrapper import in ".pipenv-wrapped" does not apply.

If startet with PYTHONPATH, that environment variable gets passed to the subprocess, so that's why the workaround is possible.

elmarx on 21 Oct 2018

@zauberpony do you have a suggestion for how this could be fixed? Do you feel this should be fixed in pipenv itself, or is a fix in Nixpkgs more appropriate?

This should have been fixed by 11d491dce56b964dffd0175f891299bee646501d.
@teozkr Could you check and close if it's fixed?

I tried steps to reproduce from the issue descripton on NixOS 19.03

nix-env -i pipenv

cd $(mktemp -d)

Failed to create virtual environment.

So that's a different error message, but still not working as expected.

Like the original error, this one also occurs with pipenv is uninstalled again and the steps to reproduce are repeated with nix run nixpkgs.pipenv instead of nix-env -i pipenv, but not with nix-shell -p pipenv instead of nix-env -i pipenv. (With nix-shell -p pipenv it seems to work as expected.)

Edit: Ah, the change from 11d491d didn't make it into the 19.03 release, yet, so I guess it is kinda expected that it won't work there, yet. I might try with the nixos-unstable channel later on.

Will this fix be included in the 19.03 stable channel?
