致命错误：第6行的C：\ wamp \ www \ myRatchetTutorial \ src \ MyApp \ Pusher.php中找不到接口'Ratchet \ Wamp \ WampServerInterface'

I am trying to run the Ratchet application demo but I got this error (in heading).

My file structure:

/bin/chat-server
/bin/push-server
/src/MyApp/Chat.php
/src/MyApp/Pusher.php
/vendor/ ..
composer.json

This is my Pusher class, where I got the error:

<?php
namespace MyApp;
use Ratchet\ConnectionInterface;
use Ratchet\Wamp\WampServerInterface;

class Pusher implements WampServerInterface {

    public function onUnSubscribe(ConnectionInterface $conn, $topic) {
    }
    public function onOpen(ConnectionInterface $conn) {
    }
    public function onClose(ConnectionInterface $conn) {
    }
    public function onCall(ConnectionInterface $conn, $id, $topic, array $params) {
        // In this application if clients send data it's because the user hacked around in console
        $conn->callError($id, $topic, 'You are not allowed to make calls')->close();
    }
    public function onPublish(ConnectionInterface $conn, $topic, $event, array $exclude, array $eligible) {
        // In this application if clients send data it's because the user hacked around in console
        $conn->close();
    }
    public function onError(ConnectionInterface $conn, \Exception $e) {
    }


        /**
     * A lookup of all the topics clients have subscribed to
     */
    protected $subscribedTopics = array();

    public function onSubscribe(ConnectionInterface $conn, $topic) {
        $this->subscribedTopics[$topic->getId()] = $topic;
    }

    /**
     * @param string JSON'ified string we'll receive from ZeroMQ
     */
    public function onBlogEntry($entry) {
        $entryData = json_decode($entry, true);

        // If the lookup topic object isn't set there is no one to publish to
        if (!array_key_exists($entryData['category'], $this->subscribedTopics)) {
            return;
        }

        $topic = $this->subscribedTopics[$entryData['category']];

        // re-send the data to all the clients subscribed to that category
        $topic->broadcast($entryData);
    }

    /* The rest of our methods were as they were, omitted from docs to save space */
}

My WampServerInterface is in:

C:\wamp\www\myRatchetTutorial\vendor\cbodenatchet\src\Ratchet\Wamp\WampServerInterface.php

I tried to reorganize this file structure to:

C:\wamp\www\myRatchetTutorial\vendor\Ratchet\Wamp\WampServerInterface.php

but still same error.

Any ideas how to fix it?

Here is my composer.json:

{
    "autoload": {
        "psr-0": {
            "MyApp": "src"
        }
    },
    "require": {
        "cboden/ratchet": "0.3.*",
        "react/zmq": "0.2.*|0.3.*"
    }
}

Push_server.php (include autoload file):

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

    $loop   = React\EventLoop\Factory::create();
    $pusher = new MyApp\Pusher;

    // Listen for the web server to make a ZeroMQ push after an ajax request
    $context = new React\ZMQ\Context($loop);
    $pull = $context->getSocket(ZMQ::SOCKET_PULL);
    $pull->bind('tcp://127.0.0.1:5555'); // Binding to 127.0.0.1 means the only client that can connect is itself
    $pull->on('message', array($pusher, 'onBlogEntry'));

    // Set up our WebSocket server for clients wanting real-time updates
    $webSock = new React\Socket\Server($loop);
    $webSock->listen(8080, '0.0.0.0'); // Binding to 0.0.0.0 means remotes can connect
    $webServer = new Ratchet\Server\IoServer(
        new Ratchet\Http\HttpServer(
            new Ratchet\WebSocket\WsServer(
                new Ratchet\Wamp\WampServer(
                    $pusher
                )
            )
        ),
        $webSock
    );

    $loop->run();

You should check the autoload file, if you are using Laravel for example, take a look at the folder: vendor/composer there should be a file called autoload_classmap and find this line:

'Ratchet\\Wamp\\WampServerInterface' => $vendorDir . '/cboden/ratchet/src/Ratchet/Wamp/WampServerInterface.php',

If the file doesn't contains anything related to Ratchet, please make composer dump-autoload from the command line
