title: Upgrading Oh My Zsh gives me 'not a git repository' error
body: <p>Since I upgrade my OSX to El Capitan when I want to update Oh My Zsh <code>upgrade_oh_my_zsh</code> I got the following error:</p>
  
  <pre><code>Upgrading Oh My Zsh
  fatal: Not a git repository (or any of the parent directories): .git
  There was an error updating. Try again later?
  </code></pre>
  
  <p>I never used git before, searching this fatal error on the internet they advice to do <code>git init</code> in the <code>/.oh-my-zsh</code> folder. After running this command a new fatal error occur when I try to run <code>upgrade_oh_my_zsh</code> again.</p>
  
  <pre><code>fatal: 'origin' does not appear to be a git repository
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists. 
  </code></pre>
  
  <p>I don't know if it has anything to do with with it but when I open the terminal (iTerm2) I also got this notification:</p>
  
  <pre><code>/Users/peter/.zshrc:1: command not found: Path
  </code></pre>
  
  <p>Anyone has experience with this or knows a solution for my problem? </p>
