Using virtualenvwrapper

• user-friendly wrapper around virtualenv

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

export VIRTUALENVWRAPPER_PYTHON=$(which python)
export VIRTUALENVWRAPPER_VIRTUALENV=$(which virtualenv)

export WORKON_HOME="$HOME/virtualenvs"
export PROJECT_HOME="$HOME/Development"

$ workon my_env
# move to correct folder
