title: Is there a yarn command that shows the path of where all of your packages are installed?
body: <p>I have multiple versions of a dependency in my package (via transitive dependencies).  I know <code>yarn why &lt;package&gt;</code> gives some clues about why the different versions are present.</p>
  <p>Is there a command that shows the exact path of where each package has been installed too?</p>
  <p>(I'm curious about both yarn 1 and yarn 2)</p>
