I had to downgrade to evenement 2.1.0 because react/zmq won't intall wit evenement 3.0

@clarkk I think your problem has been resolved. React had updated one of their libs with an API break but Ratchet's constraints have since been updated to handle this. I copy/pasted your code with the latest version of Ratchet from a fresh install and it worked.

@RonaldoMoraes Can you elaborate on your problem?

@lmfmaier I opened reactphp/zmq#40 for your issue.

[lmfmaier]

The "Argument 2 passed to ReactSocketServer::__construct() must implement interface ReactEventLoopLoopInterface, none given" error has been resolved by making changes to my source code:

Old:

$webSock = new React\Socket\Server($loop);
$webSock->listen(88, '0.0.0.0');

New:

$webSock = new React\Socket\Server('0.0.0.0:88',$loop);
