Build version control with Pythonz and virtual environment with virtualenv

virtualenv, wrapper environment settings

install

$ sudo pip install virtualenv virtualenvwrapper

Virtualenv setting in .zshrc

When the virtualenv environment is ~ / .virtualenvs

## virtualenv, virtualenvwrapper
which virtualenvwrapper.sh > /dev/null
if [ $? -eq 0 ]; then
    source `which virtualenvwrapper.sh`
    mkdir -p ~/.virtualenvs
    export WORKON_HOME=~/.virtualenvs
    export PIP_RESPECT_VIRTUALENV=true
fi

Pythonz preferences

install

$ curl -kL https://raw.github.com/saghul/pythonz/master/pythonz-install | bash

Pythonz settings in .zshrc

# Pythonz
if [ -s $HOME/.pythonz/etc/bashrc ]; then
    source $HOME/.pythonz/etc/bashrc
fi

Multiple Python version install

$ pythonz install 2.7.5
$ pythonz install 2.6.9
$ pythonz install 3.3.3

#Verification
$ pythonz list

==>
  CPython-2.6.9
  CPython-2.7.5
  CPython-3.3.3

Pythonz + virtualenv

Create virtual environment

$ mkvirtualenv -p ~/.pythonz/pythons/CPython-2.6.9/bin/python2.6 v2.6.9 && deactivate

$ mkvirtualenv -p ~/.pythonz/pythons/CPython-2.7.5/bin/python2.7 v2.7.5 && deactivate

$ mkvirtualenv -p ~/.pythonz/pythons/CPython-3.3.3/bin/python3.3 v3.3.3 && deactivate

Switch environment & delete

# activate
$ workon v2.7.5

# deactivate (to System)
$ deactivate

# remove
$ rmvirtualenv v2.6.9
