2018.11.14 regression: cannot create virtualenv

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.

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`
