Pipenv, by default will use your virtualenv folder location if you set that environment variable - which probably be a .virtualenv or .env folder in your home directory.
But sometimes you would like to have the virtualenv folder within the project folder - ie. project/.venv No sweat, pipenv supports this workflow if set the PIPENV_VENV_IN_PROJECT environment variable.
For Macs: $ export PIPENV_VENV_IN_PROJECT=1
For Windows: > set PIPENV_VENV_IN_PROJECT=1
Do note that in Windows, you can also use setx.
Then we can run either a: pipenv install or pipenv --three to get started.
