Node.js "No method 'readFilesync"

I'm trying to implement the node server from this guide: http://java.dzone.com/articles/getting-started-socketio-and . However, I've run into an issue. When I do node file.js, it spits out that Object # has no method readFilesync. I'm confused, because it's the same as in the guide and there is in fact a readFilesync method.

Here's the code:

var fs = require('fs'),
    http = require('http'),
    socketio = require('socket.io');

var server = http.createServer(function(req, res) {
    res.writeHead(200, { 'Content-type': 'text/html' });
    res.end(fs.readFilesync(__dirname + '/home/name/projects/proj/proj/templates/chat/chat.html'));
}).listen(9001, function() {
    console.log('Listening at: http://name.site.com:9001');
});

socketio.listen(server).on('connection', function (socket) {
    socket.on('message', function (msg) {
    console.log('Message Received: ', msg);
    socket.broadcast.emit('message', msg);
    });
});
