2018.11.14 regression: cannot create virtualenv

[dimbleby]

Issue description

Can't create new virtual environment.

Expected result

Run pipenv --three, say. Get a new virtual environment.

Actual result

$ pipenv --three --verbose                                                                                                                                       [7/188]

Steps to replicate

pipenv --three

I mean I suppose there's something about my environment that triggers this - because surely you wouldn't make a release that simply didn't work - but I don't know what it is. 2018.10.13 works fine.

[duplicate-issues]

Hey @dimbleby,

We did a quick check and this issue looks very darn similar to

• #3231 - 'pipenv clean' fails when running in an existing virtualenv
• #3230 - 2018.11.14 regression: pipenv fails to install editable extras
• #3229 - 2018.11.14 pipenv emits pythons errors when creating a virtualenv

This could be a coincidence, but if any of these issues solves your problem then I did a good job 😄

If not, the maintainers will get to this issue shortly.

Cheers,
Your Friendly Neighborhood ProBot

bad bot

[techalchemy]

The bot is quite aggressive... wonder if that can be tuned a bit....

It looks like it encountered an anaconda command and died attempting to run it... I’ll be cutting a bugfix release shortly, so we just need to determine which command it tried running. Presumably anaconda in which case we need to drop that from the list or bypass it in pythonfinder.

[dimbleby]

On my system - Centos 7 - anaconda is nothing to do with python

$ which anaconda
/usr/sbin/anaconda

And anaconda --help says (among other things):

Anaconda is the installation program used by Fedora,Red Hat Enterprise Linux and some other
distributions.

As a workaround you can pass the full path to the python interpreter:

pipenv --python `which python3`
