title: ReferenceError: Can't find variable: require (emulator on Windows 10)

  <p>I have ran the following command with no changes: adb reverse tcp: 8081 tcp:8081</p>
  
  <p>I am on Windows 10, using emulators (not my device). Also, I had someone who has a Mac run this with <strong>no issue</strong>. </p>
  
  <p>Thanks in advance!</p>
