sudo apt install python3.6 python3-pip

Next, we’re going to upgrade pip because OCD and install virtualenv and virtualenvwrapper.

 sudo -H pip3 install --upgrade pip
 sudo -H pip3 install virtualenv virtualenvwrapper

Edit your ~/.bashrc

 export WORKON_HOME=$HOME/.virtualenvs                    # Environments stored here
 export PROJECT_HOME=/mnt/c/Users/<username>/Code         # Path to       your Python projects
 export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3.6       # Make     Python3 the default
 source /usr/local/bin/virtualenvwrapper.sh               # Engage!

Finally load all the goodies with ''''source ~/.bashrc.''''

Bonus

I like workon <environment name> to dump me in the project directory. To do this, add the following to ~/.virtualenv/postactivate

 PROJ_NAME=$(basename $VIRTUAL_ENV)
cd $PROJECT_HOME/$PROJ_NAME
