title: npm install -g vue-cli -> coffeescript moved
body: <p>I've tried to install it using many <code>nodejs</code> / <code>npm</code> versions, on many different hosts, including a docker image:</p>
  
  <pre><code>Sending build context to Docker daemon  2.048kB

   ---&gt; Running in 5a2bc7ff05ae
  npm WARN deprecated coffee-script@1.12.7: CoffeeScript on NPM has
  moved to "coffeescript" (no hyphen)
  ^C
  </code></pre>
  
  <p>And I keep getting this error every time.<br>
  This is the official issue thread: <a href="https://github.com/vuejs/vue-cli/issues/655" rel="nofollow noreferrer">https://github.com/vuejs/vue-cli/issues/655</a><br>
  As you can see, there is not much info there. All they say is that it will be fixed in version <code>2.9.2</code>, while I'm trying to install <code>2.9.3</code>..  </p>
  
  <p>Has anyone else encountered this error? Have you dealt with it?</p>
