title: Problems with installing Tkinter
body: <p>When I try to install tinter from the command line with the command > pip install tkinter &lt; I get always the error:</p>
  
  <blockquote>
    <p>Could not find a version that satisfies the requirement tkinter (from versions: )
    No matching distribution found for tkinter &lt;</p>
  </blockquote>
  
  <p>The same result with >pip3 install tkinter&lt; 
  I'm using Python 3.6 on Mac OS10.13.3</p>
  
  <p>Any solutions? Thank you!</p>
