我尝试使用Heroku为我的 RoR 应用程序设置Errbit (Airbrake) ，遵循以下站点：
- https://github.com/errbit/errbit
- http://morizyun.github.io/blog/errbit-heroku-rails-error-ruby/（仅限日语，抱歉）
Heroku 上的部署运行良好。我可以正常登录并创建应用程序，所有设置似乎都可以。
在应用程序方面，我按照指南中的描述创建了文件：
*Gemfile:*
gem 'airbrake'
*config/initializers/errbit.rb:*
Airbrake.configure do |config|
config.api_key = 'eb81f59f77778865464da97f0e1ce5951'
config.host = 'myproject-errbit.herokuapp.com'
config.port = 80
config.secure = config.port == 443
end
我运行“捆绑安装”并在 localhost 中尝试了命令：
rake airbrake:test
好的，它可以工作（heroku 应用程序中存在的信息）。接下来，我在生产环境中部署（通过 capistrano），然后再试一次：
ssh app@xx.xxx.xxx.xxx
cd /u/myapp/path/current/
rake airbrake:test
我收到此错误消息：

（我已经使用“app”用户（部署用户）输入了命令。）
我觉得红宝石设置是错误的：
ruby version
ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-linux]
rvm list
rvm rubies
=* ruby-2.0.0-p0 [ x86_64 ]
# => - current
# =* - current && default
# * - default
所以你可以想象，当发生错误时，数据不会保存在 Errbit(Heroku) 项目中。
如果有人可以帮助我，我将不胜感激~
