React Error — Can't fix!

I am working on the last part (part 4) of the Ravenous error and all of the sudden my app started throwing an error:

  return (new fsevents(path)).on('fsevent', callback).start();

TypeError: fsevents is not a constructor

I found a few ideas on how to solve it at this thread on the React GitHub, but it’s not clear to me which approach I should be using.

Have you seen this issue before? It looks common.
