title: pip not working after installing python3 on Mac
body: <p>I installed python3 from the official website and then installed jupyter notebook. While trying to run jupyter notebook, I was getting a "command not found" error. </p>
  
  <p>I found <a href="https://github.com/jupyter/help/issues/89" rel="nofollow noreferrer">this github issue</a> and followed the instructions to delete python3 and reinstall using Homebrew instead (I've used Homebrew before).</p>
  
  <p>When trying <code>python3 -m pip install --upgrade pip</code> i get a "No module named pip" error. My <code>/usr/local/bin/</code> file shows pip, pip2, pip2.7, pip3, pip3.6.</p>
  
  <p>I have a feeling my pip is not associated with the python3 that I installed using Homebrew. How can I fix this?</p>
