  <pre><code>sudo pip install nose
  </code></pre>
  
  <p>Then got </p>
  
  <pre><code>ERROR: Could not install packages due to an EnvironmentError: [Errno 1] Operation not permitted: '/System/Library/Frameworks/Python.framework/Versions/2.7/man'
  </code></pre>
  
  <p>I was expecting to have an application installed on my Mac with which I can just double click the logo and start the application, like Chrome with that Circular google logo. What should I do from here?</p>
