Php Symfony 2试图加载“类”；IoServer"；“来自名称空间”；棘轮\服务器“；

我有这个命令：

    class SockServerCommand extends ContainerAwareCommand implements MessageComponentInterface
    {

//... methods for implementing MessageComponentInterface here

/**
         * {@inheritdoc}
         */
        protected function configure()
        {
            $this->clients = new \SplObjectStorage;

            $this
                ->setName('game_main:sock_server_command')
                ->setDescription('Hello PhpStorm');
        }

        /**
         * {@inheritdoc}
         */
        protected function execute(InputInterface $input, OutputInterface $output)
        {
            // $port = $input->getArgument('port');

            $server = \Ratchet\Server\IoServer::factory(
                new \Ratchet\Http\HttpServer(
                    new \Ratchet\WebSocket\WsServer(
                        $this
                    )
                ),
                7000
            );

            $server->run();
        }
    }

如果我运行命令

app/console game\u main:sock\u server\u command

，则会出现以下错误：

PHP Fatal error: Class 'Ratchet\Server\IoServer' not found in /var/public_html/symfony.loc/www/src/Game/MainBundle/Command/SockServerCommand.php on line 69
[2015-07-03 17:58:01] php.CRITICAL: Fatal Error: Class 'Ratchet\Server\IoServer' not found {"type":1,"file":"/var/public_html/symfony.loc/www/src/Game/MainBundle/Command/SockServerCommand.php","line":69,"level":-1,"stack":[]}

Did you forget a "use" statement for another namespace?              

game_main:sock_server_command

为什么Symfony找不到这个类？解决方案是什么？

作为示例，我将使用端口8080:
1.首先创建一个用于管理套接字连接的捆绑包：App\SocketBundle
2.创建位于以下位置的处理程序（服务）：App\SocketBundle\handler

<?php

namespace App\SocketBundle\Handler;

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class MainSocketHandler 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, $msg)
  {
    foreach ($this->clients as $client) {
        if ($from === $client) {
            $client->send("OK");
        }
    }
  }

  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();
  }
}

5.在App/SocketBundle/command处创建symfony命令

这个类存在吗？它位于哪个文件中？您是如何安装库的？该类不存在。我是作曲家需要狂饮/狂饮&&作曲家需要cboden/ratchet。
