Uncaught Error: Cannot find module 'serialport' after packaging electron app (electron-packager)

SerialPort version: 4.0.7

NodeJS Version: 6.9.4

Operating System and Hardware Platform: Windows 10 x64, intel core i3-2310M CPU @ 2.10GHz, 4GB RAM

Are you using an alternative NodeJS runtime? (eg Electron): Yes, am using electron

Summary of Problem

Hi, our app uses the node-serialport package. Works fine in development, but on packaging using electron-packager it fails with the error:

module.js:457 Uncaught Error: Cannot find module 'serialport'

Steps and Code to Reproduce the Issue

• Download starter app [angular2-electron] (https://github.com/joaogarin/angular2-electron). Edit the login page so that you can go directly to home page.
• Install node-serialport npm install serialport --save
• In home.component.ts, initialize the serialport in the import section:

...
import { Location } from "@angular/common";

declare var require: any
var SerialPort = require('serialport');

...

• Package the electron app using electron-packager by running the following command npm run package
• Go to the new created release folder in the root folder of the app and run the app by double clicking on it.

N/B: I have even tried modifing the package.json script section to:

"scripts": {
    ...
    "package-win": "electron-packager src/app --overwrite --asar=true --platform=win32 --arch=x64 --icon=src/app/dist/assets/app-icon --prune=true --out=release-builds"
  }

and

"scripts": {
    ...
    "package-win": "electron-packager src/app --overwrite --asar.unpack=\"node_modules/serialport/build/**\" --asar=true --platform=win32 --arch=x64 --icon=src/app/dist/assets/app-icon --prune=true --out=release-builds"
  }

I have tried modifying --asar.unpack to various paths --asar.unpack=\"*.node\" but still not packing the node-serialport. Any pointers on how to package the app using electron-packager and have it run in production. Am yet to make the installer.
