Installation

From python3.4 and up you should not need to install pip. This now comes pre-installed with python. That means that you can install virtualenv in both python versions by running;

python3.6 -m pip install virtualenv
python3.7 -m pip install virtualenv

Once it is installed in both python versions you can create a new virtualenv from them by running;

python3.6 -m virtualenv venv36
python3.7 -m virtualenv venv37
