node cannot find express module?

Question

I am unaware what is causing this problem, because I thought it should be working. I do have expressed installed, at least according to npm:

C:\Users\phucker\Desktop>node init.js

module.js:340
    throw err;
          ^
Error: Cannot find module 'express'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)

    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

C:\Users\phucker\Desktop>npm express -v
1.3.2

C:\Users\phucker\Desktop>

the code contained in init.js is

var express = require('express');
var app = express();

app.get('/', function(req, res){
  res.send('hello world');
});

app.listen(3000);

You need to have express installed locally in your node_modules folder. Check your node_modules and install it again if it is not there
