Node Spawn

sample.js

// node executable file phantom_sample.js

var spawn = require('child_process').spawn;
var phantom = require('phantomjs');
var excPath = phantom.path;
var path = require('path');

var args = [
  path.resolve( __dirname, 'phantom_exc.js')
];

spawn(excPath, args);

//phantom_exc.js
var system = require('system');
var webpage = require('webpage');

console.log(system, webpage);

Give that a try for your node script. :)

// node executable file phantom_sample.js

var spawn = require('child_process').spawn;
var phantom = require('phantomjs');
var excPath = phantom.path;
var path = require('path');

var args = [
  path.resolve( __dirname, 'phantom.js')
];

var phantomSpawn = spawn(excPath, args);

phantomSpawn.stdout.on('data', function (data) {
  console.log('stdout: ' + data);
});
