title: unable to run Jupyter notebook after Pip3 install
body: <p>Getting error msg in terminal </p>
  
  <pre><code>Jupyter: command not found
  </code></pre>
  
  <p>after pip3 install.
  I did some reading and it seems to have to do with the path pip installed in being different to my working directory? 
  The jupyter is installed in <code>/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages</code> 
  and my default path seems to be </p>
  
  <pre><code>export   echo $PATH
  /usr/bin:/bin:/usr/sbin:/sbin
  </code></pre>
  
  <p>I tried to move my path to where jupyter is installed by running <code>:PATH="$HOME/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/bin:$PATH"</code>
  But it still didn't work</p>
