使用rubymine调试rails应用程序

概述我有一个使用 Ruby 1.8.7的Rails应用程序,我在调试模式下运行并设置断点时收到此错误： 54749: Exception in DebugThread loop: undefined method `errmsg' for #<Debugger::ControlState:0x10e3def28>Backtrace:/Users/ohad/.rvm/gems/ruby-1.8.7- 我有一个使用 Ruby 1.8.7的Rails应用程序,我在调试模式下运行并设置断点时收到此错误：

我已经在我的Gemfile中添加了ruby-deBUG：

group :development do  gem "inaction_mailer",'0.6',:require => 'inaction_mailer/force_load'  gem 'ruby-deBUG',:require => nil  # gem 'bullet'  # gem "ruby-growl"end

解决方法 你安装了ruby-deBUG gem,将其删除.

参见this answer,只需要2个调试宝石(Ruby 1.8的版本会有所不同)：

ruby-deBUG-base (0.10.5.rc3)ruby-deBUG-IDe (0.4.17.beta16)
