2020 September 3rdPipenv environment variable LANG is not set!python

When running pipenv install this error would pop up:

Warning: the environment variable LANG is not set!

My terminal is still on bash, so I had to edit the bash_profile file:

$sudo nano \~/.bashprofile

Next is to add the following to it:

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

Then I reloaded the bash profile with: source ~/.bash_profile
