title: Parcel build command not working
body: <p>I am following the basic tutorial for <a href="https://parceljs.org/getting_started.html" rel="nofollow noreferrer">Parcel</a> to bundle js, css and image files.</p>
  
  <p>My file structure</p>
  
  <pre><code>  dist
    node_modules
    src
      - index.html
      - style.css
      - index.js
      - somemodule.js
  </code></pre>
  
  <p>When I run <code>parcel ./src/index.html</code> a server is started and the website is displayed correctly. According to the tutorial you can finalize the build using <code>parcel build index.js</code>. I expected to get this output:</p>
  
  <pre><code>  dist
      - style.css
      - index.js
      - index.html
  </code></pre>
  
  <p>But instead, after running <code>parcel build index.js</code> I get this output:</p>
  
  <pre><code>  dist
      - 4wyd98y98790.css
      - 948y59hslas8.js
  </code></pre>
  
  <p>What could possibly be going wrong? </p>
