hi, i want to implement rabbitmq in ruby

.

For that i have done the following steps:

Sudo apt-get install rabbitmq-server

sudo gem install amqp
sudo -H -u rabbitmq rabbitmq-server
 
server is working fine i.e. the broker is running completly.
I am trying to implement examples given in [https://github.com/rabbitmq/rabbitmq-tutorials/tree/master/ruby](https://github.com/rabbitmq/rabbitmq-tutorials/tree/master/ruby)
