Install Virtualenv and Virtualenvwrapper on Ubuntu 14.04

Virtualenv helps a lot when you work with various Python projects or when you have to use specific packages or different Python versions.
In this tutorial, we are going to install Virtualenv on Ubuntu 14.04 and configure it on zsh.

Install pip, virtualenv and virtualenvwrapper

sudo apt-get install -y python-pip python-virtualenv virtualenvwrapper  

Create the directory for our virtual environments

mkdir ~/.venvs  

Configure ZSH - .zshrc

Edit the file ~/.zshrc and paste the content below:

export WORKON_HOME=~/.venvs  
source /usr/share/virtualenvwrapper/  
export PIP_VIRTUALENV_BASE=~/.venvs  

Create our first virtualenv

~ ❯❯❯ mkvirtualenv myproject                                                                                                                                    ⏎
