I am using Bluemix to deploy a sample node.js app. Everything works fine if i don't require Q package inside my app code. But the app deployment fails if i require the Q package inside my code.
Here's my app code -
/*eslint-env node*/
var express = require('express'),
cfenv = require('cfenv'),
//bodyParser = require('body-parser'),
//multer = require('multer'),
Q = require('Q');
var app = express();
app.set('view engine', 'pug');
app.use(express.static(__dirname + '/views'));
app.get('/', function (req, res) {
res.render('index');
});
app.listen(appEnv.port, '0.0.0.0', function() {
console.log("server starting on " + appEnv.url);
});
However, when i check the logs Q module is indeed installed and shows as below.

NOTE: If i remove the line Q = require('Q') everything works fine and app gets deployed and started successfully. Also i have tested it locally on my machine and it works perfectly fine.
Any suggestions or solutions? Thanks!
Try the following code:
var Q = require('q');
The q module name is q, not Q.
