解决方案

经过一番思考和查阅发现可以这样解决

• 定位到homebrew目录

  cd /usr/local/Homebrew/Library/Taps/homebrew/

• 然后rm -rf homebrew-core
• 重新git clone https://github.com/Homebrew/homebrew-core.git
• 最后重新执行brew install

问题原因

可能是安装brew的过程中由于网络原因或者其他原因导致homebrew安装出现问题

rabbitmq 其他

• rabbitmq常用命令：

  brew services info   rabbitmq
  brew services stop   rabbitmq
  brew services restart   rabbitmq
  brew services kill   rabbitmq

• Web界面管理RabbitMQ
  默认是可以本地登录localhost:15672，用户名：guest；密码：guest；端口默认15672
