棘轮推送教程错误不能代表ZMQ_FD类型的流

Question

I'm trying to run Ratchet tutorial application on my localhost. I followed this tutorial http://socketo.me/docs/push , but on the last step I got this error, after I ran my push server (bin /push_server.php)

Warning: stream_select(): cannot represent a stream of type ZMQ_FD as a select()
able descriptor in C:\wamp\wwwatchet_podla_tutorialu\vendoreact\event-loop\S
treamSelectLoop.php on line 255

This is my push_server.php 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();

I'm running WampServer x 64 on Windows 7 x 64.

I found here an older post, where guy had probably the same problem as me and he fixed it by installing WampServer x32 version. I would like to avoid this solution. Does anybody know how to fix it?
