title: OS X Yosemite - iPython only acessible with sudo
body: <p>I had iPython installed on older versions of OS X. Recently I've upgraded for OS X Yosemite and I'm not being able to use iPhyton without sudo permission:</p>
  
  <pre><code>$ ipython
  -bash: /usr/local/share/python/ipython: No such file or directory
  </code></pre>
  
  <p>However if I use sudo it works. I've installed it though pip.</p>
  
  <p>How can I give to all users access to iPython?</p>
