使用带有 RabbitMQ 的 Sneakers 的 Ruby on Rails 错误

Question

我正在使用运动鞋 gem 来触发 RabbitMQ 上的操作 但我无法启动我的触发服务

我运行命令

WORKERS=MailerWorker rake sneakers:run

我得到的错误是

[INFO] 160825 14:26:46 :: LAUNCH worker

我的代码如下

# 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 在交换“test.user.login”处也有消息

我关注了这篇文章，但出现了错误 Rails: How to listen to / pull from service or queue?

我怎样才能不出错地运行运动鞋

谢谢

错误表明 ActionCable 在您的脚本中不可用，您应该在脚本中安装/要求它。
