title: npm Fetch Failed. Error Code 504
body: <p>I'm trying to implement this plugin called <a href="https://github.com/carrot/share-button" rel="nofollow">Share Button</a> from npm my running <code>https://github.com/carrot/share-button</code>. However after doing that and waiting around 5mins I get the following output:</p>
  
  <pre><code>npm ERR! fetch failed https://registry.npmjs.org/i/-/i-0.3.2.tgz
  npm WARN retry will retry, error on last attempt: Error: fetch failed with status code 504
  ⸨    ░░░░░░░░░░░░░░⸩ ⠇ fetchMetadata: WARN retry will retry, error on last attempt: Error: fetch failed with status code 504
  </code></pre>
  
  <p>Does anyone know why this would happen and a way to get round it? Thanks</p>
