title: who does npm install of webpack-dev-server require '-g'?
body: <p>Trying to run &quot;webpack-dev-server --open&quot; from VSCode bash terminal. Error: webpack-dev-server not found</p>
  <p>Why do I have to do the install with '-g'? If I install local, I get the not found error. In this case, do I have to modify the path to pick up the local install?</p>
  <pre><code>npm install webpack-dev-server -g
  </code></pre>
