title: Python: Set permissions for pip or conda in /opt directory
body: <p>I installed python via Anaconda to my <code>/opt</code> directory (I heard that's the proper way when all users should be able to use it).</p>
  
  <p>Everything is working fine so far, up to the point when I try to install packages via pip or conda. Than I get permission issues for both ways.
  When I try to do:</p>
  
  <pre><code>sudo pip install pandas-datareader
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>sudo: pip: command not found
  </code></pre>
  
  <p>and the same error results if I try to use <code>conda</code> as well.</p>
  
  <p>Does anyone have an idea how to fix that?</p>
