Class 'React\ZMQ\Context' not found

[Winnie Nakimuli]

i have done everything as according to the push tutorial, but for some reason am still getting the same error for the past two days, i did a PHP binding with zeroMQ and everything is fine. My Composer.json 

{

    "minimum-stability": "dev",

    "autoload": {

        "psr-0": {

            "MyApp": "src"

           

        }

    },

    "require": {

        "cboden/Ratchet": "0.2.*"

      , "react/zmq": "0.1.*"

    }

}

when i run composer.phar install and update all iz ok and nothing to update

and i include the  require dirname(__DIR__) . '/vendor/autoload.php'; line in my push-server.php...i have tried everything don't know what to do next

Finally, i was able to make it work, my problem was i needed a development package for Xampp not the normal package that i had installed for zeroMQ binding. Then i also i had two instances of php running one on my xampp and the other /usr/bin so everytime i run php composer.phar install it was using the php in  /usr/bin which i found out by running which php, so i removed the php in /usr/bin and then created a symbolic link to /opt/lampp/bin/php after doing this, everything else just worked great.

Thank you so much for your continuous help, am still learning but am getting there
