Build to blank screen on osx

Every time I build my electron application it is successful but when I run the application Im presented with a blank screen. Im positive that it is finding my main.js and using it as modifications here result in changes in the built application. Any help with this would me much appreciated it.

Here is my build command

$ sudo electron-packager . foo --platform=all --arch=x64 --version=0.31.2 --overwrite 

Here is my main.js

var app = require('app');  // Module to control application life.
var BrowserWindow = require('browser-window');  // Module to create native browser window.

// Report crashes to our server.
require('crash-reporter').start();

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
var mainWindow = null;

// Quit when all windows are closed.
app.on('window-all-closed', function() {
  // On OS X it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
    app.quit();
});

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
app.on('ready', function() {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 1400, height: 700});



  // and load the index.html of the app.
  mainWindow.loadUrl('file://' + __dirname + '/templates/index.html');

  // Open the DevTools.
  // mainWindow.openDevTools();

  // Emitted when the window is closed.
  mainWindow.on('closed', function() {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null;
  });
});

I have the exact same problem as gillyb running electron-packager 5.2.1 and using this command: electron-packager . myapp --ignore=“node_modules/(electron-packager|electron-prebuilt)” --platform=win32 --arch=ia32 --version=0.36.3 --overwrite --asar=false

Not sure if this is related to your problem, but please check Console it shows some errors log if any strange things occur. Mine is because of Uncaught Error https://github.com/onmyway133/blog/issues/145
