For additional information regarding installation of pip. See http://www.pip-installer.org/en/latest/installing.html

Using Pip

1. Within the Slicer python interactor: 

 ./Slicer --no-main-window --disable-cli-modules --disable-loadable-modules --disable-scripted-loadable-modules --show-python-interactor

2. Try to install a package 

 import pip
 pip.main(['install', 'pygments'])
