I am trying to get a simple sample working of running Ace inside of an Electron app.

I started by copying the 1.4.12 version of ace-builds/src-noconflict directory contents into app/lib/ace in my app. The contents of app/index.html is:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width,initial-scale=1">
  <title>Ace Editor in Electron</title>
  <style type="text/css" media="screen">
      #editor { position: absolute; top: 0; right: 0; bottom: 0; left: 0; }
  </style>
</head>
<body>
  <div id="editor">function test () {}</div>
  <script src="lib/ace/ace.js" type="text/javascript" charset="utf-8"></script>
  <script>
    const editor = ace.edit('editor')
    editor.setTheme('ace/theme/twilight')
    editor.setMode('ace/mode/javascript')
  </script>
</body>
</html>

When I run the electron app, I see the following errors in the Developer Tool console:

Uncaught TypeError: Cannot read property 'inherits' of undefined
    at ace.js:6514
    at lookup (ace.js:141)
    at _require (ace.js:75)
    at req (ace.js:138)
    at ace.js:6541
    at lookup (ace.js:141)
    at _require (ace.js:75)
    at req (ace.js:138)
    at ace.js:9215
    at lookup (ace.js:141)
Uncaught TypeError: ace.edit is not a function
    at index.html:15

Surely I must be doing something stupid. I searched the Internet looking for examples of running Ace inside of Electron but the few I found were very out of date (and had similar errors).
