Errore node.js

[Marduk87]

Salve sono nuovo(forum e su node.js)seguendo il tutorial sul sito ho creato il primo "programmino" in node js

var http = require('http');
var server = http.createServer(function(req,res){
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('First app');
}


server.listen(1337, '127.0.0.1');


console.log('Server running at http://127.0.0.1:1337/');

eseguo con node path_to_file/first_app.js e mi restituisce questo sulla
chiamata server.listen(1337, '127.0.0.1');:
