body: <p>I am trying to install a library package to python but I get the following error:</p>
  
  <pre><code>OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/PackageName'
  </code></pre>
  
  <p>I've looked online and tried the following, but it doesn't seem to work:</p>
  
  <pre><code>chown -R $USER /Library/Python/2.7/site-packages/pync
  </code></pre>
  
  <p>and also:</p>
