Setting virtualenv and install Django (MACOSX)

Question

I don't know why I can't create virutalenv for my projects.

I create the folder and type the command to install Django

pipenv install Django

But I have an error I can't identify what is it.

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

So sorry, I am beginner in Django and I am following the Willian S. Vicent book (Django 2.0)

After that the book ask to type:

$ pipenv shell

and start my project. I could do it before, but now I don't know what is happening.

Thanks,

This is a common issue in MacOS, The issue is mentioned here a long with the solution. https://pipenv.kennethreitz.org/diagnose/#valueerror-unknown-locale-utf-8

To make the long story short, There are some variables are missing in your machine which are LC_ALL and LANG. You have to add this to your ~/.bash_profile file.

so what you need to do is open this file with your favorit editor and add those line

export LC_ALL='en_US.UTF-8'
export LANG='en_US.UTF-8'

After you add those Env Variables, you will need to re activate this file. So you need to run

> source ~/.bash_profile
