module.exports “Module is not defined”

RequireJS cannot load CommonJS modules as-is. However, there is a minimal modification you can make to them to load them. You have to wrap them in a define call like this:

define(function (require, exports, module) {

  module.exports = {
    Combobox: require('./combobox'),
    Option: require('./option')
  };

});

If you have a bunch of modules you need to convert, or if you are using a third-party library written in the CommonJS pattern and want to convert it as part of a build process, you can use r.js to perform the conversion for you.
