title: Ipython no readline available and pip install readline error
body: <p>I installed ipython but it doesn't have the readline option. I first downloaded gnu readline and compiled and installed. DIdn't know whether it was a proper solution but was the first thing I thought of. It still wouldn't work to no avail with the same error as before:</p>
  
  <pre>
  WARNING: Readline services not available on this platform.
  WARNING: The auto-indent feature requires the readline library
  </pre>
  
  <p>Then I tried using pip install readline and I get the error below. Any help would be appreciated:</p>
