NameScape錯誤。停留在 'MyApp的\聊天'

Question

得到錯誤的棘輪簡單的例子：

Fatal error: Uncaught Error: Class 'MyApp\Chat' not found

我的文件結構是這樣的：

root\composer.json 
root\bin\chat-server.php 
root\src\MyApp\Chat.php 

Composer.json是

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

聊天-server.php是

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

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

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

    $server->run(); 

和Chat.php是

<?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) { 
    } 
} 

我曾嘗試以下，但還是現在工作： PHP Fatal error: Class 'MyApp\Chat' not found in /MyApp/chat-server.php

檢查自動加載命名https://getcomposer.org/doc/04-schema.md#psr-0

它應該是這樣的：

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

And do

composer dump-autoload
