title: Cannot upgrade pip 9.0.1 to 9.0.3 - requirement already satisfied
body: <p>I'm trying to update <code>pip</code> using <code>pip install --upgrade pip</code>, but I get a "requirement satisfied" error and an "outdated version" message at the same time</p>
  
  <pre><code>$ pip install --upgrade pip
  Requirement already up-to-date: pip in 
  /Users/user/Envs/proj/lib/python2.7/site-packages
  You are using pip version 9.0.1, however version 9.0.3 is available.
  You should consider upgrading via the 'pip install --upgrade pip' 
  command.

  <p>How do I update?</p>
