Add python packages

[dqminh]

This will install

• Python 2.7.6
• Python 3.3.4
• Pip and Setuptools ( based on python 2.7.6 )
• Virtualenv ( based on python 2.7.6 ), but you can use this to switch python version for a project to get compatible pip and setuptools.

I'm getting this error running pip:
