electrify:meteor:index@client: cannot initialize connection. Did you npm install -g electrify?

hi.
At first. thank you for good package. this is very useful.

I`m newbie developer.. and not good talking with english... sorry.

I`m developing some meteor web app and I want to export client side code to desktop app with electron.
so, I tried with your good package, electrify.
build was completed successfully.

but, I tried to test with electrify.methods, electron app show me below error message.

I pacakged my app with electrify command

electrify package --settings settings-electron-electrify-dev.json --output=$APP_PATH -- --icon=$ICON_PATH --app-version=$VERSION

when I run server, this log is shown.
I think this logs are occurred when socket is opened, isn`t it?
if so, is this electron app(client side) problem?

GET /electrify/info 3ms 200
GET /electrify/594/n5pxxchf/websocket 2ms (unfinished)
electrify:meteor:index@server: connection is open

Here is my index.js code

app.on('ready', function() {
  // electrify start
  electrify.start(function(meteor_root_url) {
    // creates a new electron window
    window = new browser({
      width: 1200, height: 900,
      'node-integration': false,                    // node integration must to be off
      webPreferences: {
        'allowDisplayingInsecureContent': true,     // to show insecure contents
        'allowRunningInsecureContent': true
      },
    });

    // open up meteor root url
    window.focus();
    window.loadURL(meteor_root_url);

    // open development tools
    window.webContents.openDevTools();

    // open web page smoothly
    window.once('ready-to-show', function(){
      window.show();
    });
  });
});

electrify.methods({
  'hello.world': function(firstname, lastname, done) {
    //do something
    done(null, "Hello " + firstname + ' ' + lastname + "!");
  }
});

and here is my electrify.method call

// coffeescript code
// isElectron() is just my method. check electron chromuim env
if Meteor.isClient
  if isElectron()
    console.log "this is Electron?", isElectron()
    Electrify.call 'hello.world', ['test1', 'test2'], (err, msg) ->
      console.log "err?", err
      console.log "msg?", msg

and I installed electrify

xxxx@xxxx$ npm list --depth=0 -g

and I installed arboleya:electrify

meteor add arboleya:electrify

and then, when I run the electron app, got this error message
// error when run electron app

electrify:meteor:index@client: cannot initialize connection. Did you `npm install -g electrify`?
install it and try running your meteor app with `electrify` npm command

// error when I call Electrify.call('hello.world', ....)

err? Error: Cannot call methods, socket connection not initialized at (...)
msg? undefined

my develop env

os: Ubuntu 14.04 LTS
npm v2.15.8
node v4.4.7
meteor v1.4.2.3
