websocketのサーバー構築時にエラーが出る

Question

コード
{
    "autoload": {
        "psr-4": {
            "MyApp\": "src"
        }
    },
    "require": {
        "cboden/ratchet": "^0.4"
    }
}

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

class Chat implements MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(ConnectionInterface $conn) {
        // Store the new connection to send messages to later
        $this->clients->attach($conn);

        echo "New connection! ({$conn->resourceId})\n";
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        $numRecv = count($this->clients) - 1;
        echo sprintf('Connection %d sending message "%s" to %d other connection%s' . "\n"
            , $from->resourceId, $msg, $numRecv, $numRecv == 1 ? '' : 's');

        foreach ($this->clients as $client) {
            if ($from !== $client) {
                // The sender is not the receiver, send to each client connected
                $client->send($msg);
            }
        }
    }

    public function onClose(ConnectionInterface $conn) {
        // The connection is closed, remove it, as we can no longer send it messages
        $this->clients->detach($conn);

        echo "Connection {$conn->resourceId} has disconnected\n";
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";

        $conn->close();
    }
}

コード
<?php
use Ratchet\Server\IoServer;
use MyApp\Chat;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;

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

$server = IoServer::factory ( new HttpServer( new WsServer( new Chat () ) ), 8080 );
$server->run ();

サーバーを立ち上げようとして、cmdで

php chat-server.phpを入力すると

Fatal error: Uncaught Error: Class 'Ratchet\Server\IoServer' not found in C:\tutorial\websocket\bin\chat-server.php:9
Stack trace:
#0 {main}
thrown in C:\tutorial\websocket\bin\chat-server.php on line 9

とエラーが出ます

ディレクトリの階層は
├── bin
│ └── chat-server.php
├── src
│ └── MyApp
│ └── Chat.php
└── vendor
├── autoload.php
├── composer
│ ├── autoload_classmap.php
│ ├── autoload_namespaces.php
│ ├── autoload_psr4.php
│ ├── autoload_real.php
│ ├── ClassLoader.php
│ └── installed.json

です。
改善点を教えてください。

Answer 1

1.　Ratchetインストール出来ているかvendorの中を見て確認
2.1　composer使っているなら、composer dump-autoloadをし直してみる
2.2　php ~/composer.phar require cboden/ratchetで入れたならautoloadのファイルを確認する
3.　Ratchetに書かれているnamespaceが違う可能性とか、Ratchet自体を疑ってみる
Ratchet使った事ないので的外れかもしれないが
