Cheat Sheet for virtualenvwrapper

This is what I did to set up my python development system on my mac

First Steps:

1. brew install python, python3
2. pip --user install virtualenvwrapper

Add this to .zshrc

# everything for virtualenvwrapper
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python2
export WORKON_HOME=~/Envs

source /usr/local/bin/virtualenvwrapper.sh

## Helper Commands
mkvenv2() {mkvirtualenv -p $which=python2 "$*";}
mkvenv3() {mkvirtualenv -p $which=python3 "$*";}

## better exit:
alias workoff="deactivate"
