notificationListener's app() call hangs

[drewlustro]

Hi, I am not sure what is causing this issue, but but the constructor always hangs due tonotificationListener(). I put in sanity logging throughout the code, and it appears to hang on this block:

let runLoop = () => {
  let pool = $.NSAutoreleasePool('alloc')('init');

  try {
      // ✅ GETS HERE OK (does next line take forever sometimes?)
      app('nextEventMatchingMask', $.NSAnyEventMask.toString(),
          'untilDate',             $.NSDate('distantFuture'),
          'inMode',                $.NSDefaultRunLoopMode,
          'dequeue',               1);
      //  ❌ FAILS TO GET HERE
  } catch(e) {
      // ❌ALSO FAILS TO GET HERE 
      errorCallback(e);
  }

  pool('drain');
  setTimeout(runLoop, 500);
}

Also, the code directly after including nowplaying never executes:

const nowplaying = require('nowplaying');
console.log('does not get here :( – assume constructor at fault?');

Basically, the built-in callbacks fire within setupNotifications, but I am never able to attach nowplaying.on() listeners in my main code because the constructor for NowPlaying locks the process execution.

I have tried the following versions of node:

• v6.13.0 LTS
• v7.10.1
• v8.9.4 LTS

On macOS High Sierra 10.13.3 (17D102)

Is there possibly a missing library I need through brew? I have libffi. It spews a fair amount of warnings upon install, but it has worked fine for my ffmpeg installation.
