title: Nuxt.js default layout not being applied
body: <p>I'm brand new to using Nuxt.js, and having an issue: When I created my project, the layouts folder wasn't generated automatically as documented. I added it manually, but default.vue is not being applied anywhere. Here is <code>layouts/default.vue</code>:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;template&gt;
    &lt;div&gt;
        &lt;AppHeader/&gt;
        &lt;Nuxt/&gt;
    &lt;/div&gt;
  &lt;/template&gt;
  </code></pre>
  <p>I've tried things such as manually setting <code>default</code> as the layout in pages and manually importing the <code>AppHeader</code> component in <code>default.vue</code> (although this is definitely not the issue as other HTML I put there doesn't get rendered either). Not sure what's going wrong here, scratching my head. Using <code>nuxt 2.15.7</code>. If there's any additional detail needed please let me know what and I'll gladly provide, thanks.</p>
