ZSH Virtualenv and Virtualenvwrapper setup

zsh-virtualenv-setup.md

### Installing global Python & Pip Use Brew brew install python

That'll install both Python, PIP and setuptools. If for some reason it didn't install PIP you can do via

curl https://bootstrap.pypa.io/get-pip.py > get-pip.py
sudo python get-pip.py

c/f MacOSX setup gitbook

(Side note that you should install multiple versions of Python via Pyenv rather than Brew to avoid any bad Python conflicts)

Installing Virtualenv & Virtualenvwrapper

pip install virtualenv virtualenvwrapper

You'll need to tell ZSH where virtualenvs need to be put

In ~/.zshrc add

# Virtualenvwrapper things
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

Showing the virtualenv name

By default the ZSH virtualenv plugin hides the virtualenv name. I've no idea why...

nano ~/.oh-my-zsh/plugins/virtualenv/virtualenv.plugin.zsh

Within that file you'll see

# disables prompt mangling in virtual_env/bin/activate
export VIRTUAL_ENV_DISABLE_PROMPT=1

Hash out export VIRTUAL_ENV_DISABLE_PROMPT=1 and reload ZSH.

Test that all working by doing something like

~ mkvirtualenv test2

You should see
