我试图通过以下两种方式安装基本的ruby教程：
gem install bunny --version ">= 2.5.1"
和
brew install rabbitmq
然后运行sender.rb文件。
然后我收到此错误：
W, [2016-11-16T19:17:28.891581 #96531] WARN -- #<Bunny::Session:0x7ff56e055120 guest@127.0.0.1:5672, vhost=/, addresses=[127.0.0.1:5672]>: Could not establish TCP connection to 127.0.0.1:5672: Connection refused - connect(2) for 127.0.0.1:5672

有任何帮助吗？谢谢！
