pipenv Warning: the environment variable LANG is not set!

Solvement:
terminal instructions input:

This seems to be related to pipenv being installed to your Python 3.7 environment.

This may be considered a bug in pipenv or pew.

I was able to reproduce by installing pipenv into my python 3.7 environment and attempting install after unsetting those environment variables:

$ pip3.7 install --user pipenv
$ unset LANG
$ unset LC_ALL

$ ~/Library/Python/3.7/bin/pipenv --rm

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

@iblueer what are the values of LANG and LC_ALL that are defaulted in your shell?

by default, mine are showing as

$ echo $LANG
en_US.UTF-8
$ echo $LC_ALL

[iblueer]

Actually.....blank.

Closing as stale.
