title: Jupyter notebook command does not work on Mac
body: <p>I installed jupyter using pip on my macbook air. Upon trying to execute the command <code>jupyter notebook</code>, I get an error </p>
  
  <pre><code>jupyter: 'notebook' is not a Jupyter command
  </code></pre>
  
  <p>I used the --h option to get a listing of all jupyter commands and indeed, 'notebook' is not one of the commands. I am running python 2.7 and it was already installed before I installed jupyter. </p>
  
  <p>I searched on google and I see a similar problem some people have faced with the latest version of jupyter but I don't see any solutions. Can somebody point me in the right direction?</p>
  
  <p><code>which -a pip</code>: /usr/local/bin/pip</p>
  
  <p><code>which -a jupyter</code>: /usr/local/bin/jupyter</p>
