ruby-on-rails-3 - 错误——: uninitialized constant Airbrake (NameError)

Question

我正在处理一个 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，然后当我使用 capistrano 进行部署时，我在 unicorn 中遇到了以下错误生产日志:

我注意到 airbrake gem 与所有其他 gem 一起安装在 shared/bundle/ruby/1.9.1/gems 中。

在生产中，我正在运行带有 unicorn 的 Ubuntu 12.04 x64 和 nginx 和 ruby​​ 1.9.3-p194，以及这个 gems

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) 

还尝试停止 nginx、unicorn 然后重新启动它们，但没有用

我希望有人能帮我解决这个问题

更新我的包后我遇到了类似的错误。

似乎您必须在您的 airbrake 初始值设定项(config/initializers/airbrake.rb 或 config/initializers/errbit.rb)中要求 rake_handler:

require 'airbrake/rake_handler'
