Node.js - express hello world example error

Question

I try to learn node.js, and I want to use express framework for it, but when i copy and paste hello world example from expressjs.com page, it shows error:

/home/tomek/dev/node/express_server.js:1
uire, module, __filename, __dirname) { var app = require('express').createServ
                                                                    ^
TypeError: undefined is not a function
    at Object.<anonymous> (/home/tomek/dev/node/express_server.js:1:92)
    at Module._compile (module.js:449:26)
    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:349:32)
    at Function.Module._load (module.js:305:12)
    at Function.Module.runMain (module.js:490:10)
    at startup (node.js:124:16)
    at node.js:807:3

I've installed express through npm and it looks ok. Its in node_modules folder in app's root directory.

createServer is depracated. I dont know if server will not run, or just ping You with a warning, but we cant tell anything, as You didnt paste Your code.

If You use express 4, You can create server instance:

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

instead of createServer.

here is official guide for express: http://expressjs.com/guide.html

You can also check for ie this link: http://scotch.io/tutorials/javascript/build-a-restful-api-using-node-and-express-4 guide for whole restful api tutorial as good example of creating server with some routing in new express (lot of tutorials are outdated).
