Cannot find module nodeJS - node.js

Question

Hello I'm having a silly problem but I can't find the solution. When I try start my localhost I get an error saying this :
Error: Cannot find module 'passport'
Require stack:
- D:\Other\Projects\Code\Powershell\shopping-cart\config\passport.js
- D:\Other\Projects\Code\Powershell\shopping-cart\routes\index.js
- D:\Other\Projects\Code\Powershell\shopping-cart\app.js

}
I understand that it is not finding the passport.js file, I have checked the path name more than 10 times and I saw another problem where the guy had not installed the passport module, so I did that as well but it is still throwing the same error. This is what my index.js looks like :
var express = require('express');
var router = express.Router();
var Product = require('D:/Other/Projects/Code/Powershell/shopping-cart/models/product');
var csrf = require('csurf');
var passport = require('D:/Other/Projects/Code/Powershell/shopping-cart/config/passport.js');
var csrfProtection = csrf();
router.use(csrfProtection);
/* GET home page. */
router.get('/', function(req, res, next) {
Product.find(function(err, docs) {
var productChunks = [];
var chunkSize = 3;
for (var i = 0; i < docs.length; i += chunkSize) {
productChunks.push(docs.slice(i, i + chunkSize));
}
res.render('shop/index', { title: 'Shopping Cart', products: productChunks });
});
});
router.get('/user/signup', function (req, res, next) {
res.render('user/signup', {csrfToken: req.csrfToken()});
});
router.post('/user/signup', passport.authenticate('local.signup', {
successRedirect: '/user/profile',
failureRedirect: '/user/signup',
failureFlash: true
}));
router.get('/user/profile', function(req, res, next) {
res.render('user/profile');
});
module.exports = router;
Any help would be appreciated, thanks! Also , I have another problem , can I post another question in like one hour? (is it allowed to have more than 1 questions posted?)
