Ruby on Rails的错误使用运动鞋与RabbitMQ的

我使用的运动鞋的宝石来触发的RabbitMQ 的行动，但我不能启动我的服务触发Ruby on Rails的错误使用运动鞋与RabbitMQ的

我运行命令

WORKERS=MailerWorker rake sneakers:run

，我得到了误差

我的代码如下所示

# Rakefile 
require_relative 'config/application' 
require 'sneakers/tasks' 

Rails.application.load_tasks 


# config/initializers/sneakers.rb 
Sneakers.configure({}) 
Sneakers.logger.level = Logger::INFO 

# app/workers/mailer_worker.rb 
require 'sneakers' 
class MailerWorker 
    include Sneakers::Worker 

    from_queue "test.user.login", env: nil 

    def work(raw_post) 
    p "you are successful in this queue! #{raw_post.to_s}" 
    ack! # we need to let queue know that message was received 
    end 
end

我的RabbitMQ也有消息在交换“test.user.login”

我遵循这个文章，但发生的错误 Rails: How to listen to/pull from service or queue?

如何运行的球鞋没有错误

感谢

这是有帮助的http://stackoverflow.com/questions/34396006/uninitialized-constant-actioncableserverconfigurationapplicationcable –

嗨@HieuPham，感谢我已经加入这一行需要“action_cable” 到文件“的config/application.rb中' 它运作良好 –
