Virtualenvwrapper makes it easier to use Python's virtualenv

1. Install the following packages. I still need to use Python 2. If you want to use Python 3 just remove the 2 below:
   

   $ sudo pacman -Sy
   $ sudo pacman -S python-virtualenvwrapper python2-virtualenv python2-pip

2. Introduce virtualenv in your .bashrc:
   

   $ nano ~/.bashrc
   export WORKON_HOME=$HOME/.virtualenvs
   source /usr/bin/virtualenvwrapper.sh

3. Create a project e.g. myProject in virtualenv:
   

   $ mkvirtualenv myProject --python=/usr/bin/python2
   $ pip install sphinx

4. Other virtualenv commands:

• $ workon myProject        # activate the virtualenv called myProject

• $ deactivate              # deactivate the current virtualenv

• $ rmvirtualenv myProject  # delete the current virtualenv
