title: Is there a way to find out, with a command line, if a pypi package had installed also in /usr/local/bin?
body: <p>I know, for example, that <code>python3 -m pip install -U mypy</code> will install <code>mypy</code> and <code>mypyc</code> in <code>/usr/local/bin</code>.</p>
  <p>So, essentially, I like to know if there's a command line that could tell me, among all my <code>pip list</code> packages, which ones are doing something in <code>/usr/local/bin</code> other than just the <code>site-packages</code> folder.</p>
