在C：\ wamp \ www \ bin \ chat-server.php中找不到“MyChat \ Chat”类

Question

I am trying to implement the basic chat application from http://socketo.me/docs/hello-world, however I keep getting this error. I tried to move files around, but with no success, but I am quite sure that I don't put the files in the right place. I'm completly new to composer and websockets and psr-0 and I still have a lot to learn about PHP. Here are my path tree and my sources:

C:\wamp\www\
        bin
           chat-server.php
        src
            MyChat
                Chat.php
        vendor
           {dependencies}+autoload.php
        composer.json
        composer.phar
        composer.lock

Chat.php

<?php
namespace MyChat;
require dirname(__DIR__) . '\vendor\autoload.php';
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class Chat implements MessageComponentInterface
{
    protected $clients;
    function __construct()
    {
        $this->clients=new \SplObjectStorage();
    }
    function onOpen(ConnectionInterface $conn)
    {
        $this->clients->attach($conn);
        echo "New connection! ({$conn->resourceId})
";
    }
    function onClose(ConnectionInterface $conn)
    {
        echo "Connection closed: {$conn->resourceId} 
";
        $this->clients->detach($conn);
    }
    function onError(ConnectionInterface $conn, \Exception $e)
    {
        echo "An error has occured: {$e->getMessage()}. Closing connection... 
";
        $conn->close();
    }
    function onMessage(ConnectionInterface $from, $msg)
    {
        $receivers=count($this->clients)-1;
        foreach($this->clients as $client)
        {
            if($client!=$from)
            {
                $client->send($msg);
            }
        }
    }
}

chat-server.php

<?php
require dirname(__DIR__) . '\vendor\autoload.php';
use Ratchet\Server\IoServer;
use MyChat\Chat;
$server= IoServer::factory (new Chat() ,8080,'0.0.0.0');//0.0.0.0 is default, means accept all connections
$server->run();

composer.json

{
    "require": {
        "cboden/Ratchet": "0.2.*"
    },
    "autoload": {
        "psr-0": {
            "MyChat": "src"
        }
    }
}

My php.exe is in C:\wamp\bin\php\php5.4.12 . I would be really thankful for a suggestion, I can't really spot where am I mistaken.

This is a little late but it looks like you are using composer, so you may need to run that installer?

From your directory try running each of these and see if that helps:

./composer.phar install --dev
./composer.phar update
