title: How to add python support for vim without destroying up all the plugins?
body: <p>I started using vim earlier this summer and have recently started to add plugins. Todays challenge is to install YouCompleteMe. </p>
  
  <p><strong>Problem:</strong> During the installation process I noticed that my vim version (7.4) doesn't have support for python/python3. </p>
  
  <p><strong>Question:</strong> How can I fix this without messing up all my plugins/.vimrc file? </p>
  
  <p>Will a clean install even affect my plugins/.vimrc?
  I read some where that I should install 'vim-nox'.. Should I?</p>
  
  <p><strong>My setup:</strong> Ubuntu 16.04. Vim 7.4. Plugins are installed via Pathogen.</p>
  
  <p>Thanks in advance for your replies! 
  Kind regards, Edvin</p>
