title: How do I install next vuetify?
body: <p>I want to install the newest release of vuetify (2.0.0-beta.0)
  I have a project made with Vue Cli 3.7.0 and with Vuetify 1.5.X
  I've tried some ways to install it, and I wasn't successful.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Steps that I've followed:</p>
  
  <ul>
  <li>Update vuetify: <code>npm install -S vuetify@2.0.0-beta.0</code></li>
  <li>Install sass: <code>npm i -D sass</code></li>
  <li>Delete <code>styl imports</code> in vuetify.js</li>
  <li>Add <code>export default new Vuetify()</code> in vuetify.js</li>
  <li>In main.js</li>
  </ul>
  
  <pre><code>add new Vue({
    ...
    vuetify, // &lt;- this
    ...
  })
  </code></pre>
  
  <p>When I run the code, the error I get is: </p>
  
  <pre><code>[Vue warn]: Error in getter for watcher "isDark": "TypeError: Cannot read property 'dark' of undefined"
  
  found in
  
  ---&gt; &lt;VApp&gt;
         &lt;App&gt; at src/App.vue
           &lt;Root&gt;
  </code></pre>
  
  <p>I'm not using "dark" property, and the problem is in the App.vue, where I only have a component and anything else, I don't have vuetify code there.</p>
