title: Why is my react native not opening a simulator?
body: <p>I'm using React Native and Linux to create a test app.</p>
  <p>When I type <code>npm start</code> to the command line. I get the below message.</p>

  <p>However no &quot;simulator&quot; or &quot;server&quot; pops up showing me the app.</p>
  <p>When I click reload I get the warning message.<code>warn No apps connected. Sending &quot;reload&quot; to all React Native apps failed. Make sure your app is running in the simulator or on a phone connected via USB.</code></p>
