I am trying to find out why my virtualenv and/or virtualenv wrapper - installed using pip using homebrew - cannot be foun
(Mac / Linux specific)
So I got an error message when I did a pip3 install --user --upgrade virtualenv telling me that I did not have Users/home/Library/Python/3.7/bin in my PATH. So I simply added it.
If this is on the Mac, the following did it for me
vi ~/.bash_profile
PATH="/Users/home/Library/Python/3.7/bin:/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
restart your terminal and type virtualenv env and that should do it.
