Ratchet Fatal Error: Class 'Myapp Chat' not found in C: wamp www bin chat-server.php

Question

I’m trying to learn how to use the new Html5 API, Websocket, and I decided to start testing Ratchet, which is a php library. Anyway, I followed all the steps of this tutorial to create a basic chat http://socketo.me/docs/hello-world and when running on the terminal it does not find the Chat.php. class. The file structure is like this:

bin
   chat-server.php
src
   MyApp
      Chat.php
vendor
   autoload.php
   (...)
composer.json
composer.lock

My files are like this:

Composer.json

{
  "autoload": {
    "psr-0": {
        "MyApp": "src"
    }
 },
 "require": {
    "cboden/ratchet": "0.3.*"
 }
}

chat-server.php

<?php
use Ratchet\Server\IoServer;
use MyApp\Chat;

require dirname(__DIR__) . '/vendor/autoload.php';

$server = IoServer::factory(
    new Chat(),
    8080
);

$server->run();

Chat.php

<?php
namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class Chat implements MessageComponentInterface {
    public function onOpen(ConnectionInterface $conn) {
    }
    public function onMessage(ConnectionInterface $from, $msg) {
    }
    public function onClose(ConnectionInterface $conn) {
    }
    public function onError(ConnectionInterface $conn, \Exception $e) {
    }
}

ps: I found on forums some similar issues, but no procedure solved

I was with the same problem, but I managed to solve it as follows, after doing all that you did, enter again in the folder of your project via terminal and run: composer update after that run the server with the command also in the terminal php bin/chat-server.php
