title: Why is pip not working for me?
body: <p>Observe how I install wstool with pip, and then still cannot invoke it from the CLI. I put all the various paths there too. Can someone see my error? </p>
  
  <pre><code>bash-3.2$ echo $PYTHONPATH
  /usr/local/opt/python/libexec/bin/python
  bash-3.2$ sudo -H python -m pip install -U wstool
