title: "npx react-native start" hangs
body: <h3>Introduction</h3>
  <p>I'm attempting to create a Hello World style program with React Native 0.63.3 using the <a href="http://reactnative.dev/docs/environment-setup" rel="noreferrer">official docs</a>. I'm using to the <em>React Native CLI Quickstart</em> path in that link.</p>
  <h3>What I've Done So Far</h3>
  <p>I've gotten to the section:<br />
  <strong>Running your React Native application</strong><br />
  <strong>Step 1: Start Metro</strong></p>
  <p>And I've run:</p>
  <pre><code>npx react-native start --verbose
  </code></pre>
  <p>And I get the following output:</p>
  <pre><code>               ######                ######
