title: How do I properly add 'script wheel' to python path?
body: <p>I just installed Python 3.7 from <a href="https://www.python.org/" rel="nofollow noreferrer">python.org</a>. I followed this <a href="https://stackoverflow.com/questions/49704364/make-python3-as-my-default-python-on-mac">StackOverflow post</a> to change my default Python to Python 3. From there I ran the Update Shell Profile.command and Install Certificates.command
  (Finder > Applications > Python 3.7).</p>
  
  <p>Then I found that I couldn't run the pip command </p>
  
  <pre><code>&gt; $ pip --version
  
  &gt; -bash: pip: command not found
  </code></pre>
  
  <p>Subsequently I ran the following 2 commands..</p>
  
  <pre><code>&gt; $ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
  &gt; 
  &gt; $ python get-pip.py

  <p>This is what I don't understand</p>
  
  <pre><code>&gt; The script wheel is
  &gt; installed in '/Users/kevinturney/Library/Python/2.7/bin' which is not
  &gt; on PATH.   
  
  &gt; Consider adding this directory to PATH or, if you prefer to
  &gt; suppress this warning, use --no-warn-script-location.
  </code></pre>
  
  <p>What is the wheel and how do I add this to the correct path?</p>
  
  <pre><code>&gt; $ which python
  
  &gt; /usr/local/opt/python/libexec/bin/python
