我正在开发一个rails 3.2.8项目，我刚刚安装了airbrake gem来跟踪错误，在开发中我做了airbrake安装步骤，然后当我用capistrano进行部署时，我得到了以下错误在独角兽生产日志中：

我注意到airbrake gem安装在shared / bundle / ruby / 1.9.1 / gem中与所有其他宝石一起。
在制作中，我正在运行一个Ubuntu 12.04 x64，独角兽用nginx和ruby 1.9.3-p194运行，带有这个宝石
Using airbrake (3.1.4)
Using capistrano (2.12.0)
Using bundler (1.1.4)
Using rails (3.2.8)
Using unicorn (4.3.1)
还试图阻止nginx，unicorn然后再次启动它们，但它没有用
我希望有人可以帮助我

更新我的包后发生了类似的错误。
您的airbrake初始化程序（config / initializers / airbrake.rb或config / initializers / errbit.rb）似乎需要rake_handler：
require 'airbrake/rake_handler'

与上面的knagode类似。我需要添加rake处理程序。
require 'airbrake/rake_handler'
我还需要再次停止并启动服务器。
cap <env> deploy:stop
cap <env> deploy:start
重启功能似乎没有发现它。

以这种方式重新启动服务器对我有帮助：
