Unit is a placeholder return value for functions that don't actually return a meaninfgul value. It is the default return type for any function if one is not specified explicitly. Nothing is a placeholder return value for functions that should never actually return (ie they throw an exception or have infinite loop). Good SO discussion on differences.
I do this infrequently enought that I always forget how to do it. Note that I've finally decided to move away from virtualenvwrapper (workon, mkvirtualenv, etc) since it didn't play nicely with the python versions set by pyenv.
Only necessary if this is a new laptop
brew install pyenv
brew install pyenv-virtualenv
