ruby-on-rails - 无法使用 RVM、Ruby 1.9.2 和 Rails 3 运行 RubyMine 调试器

Question

我已经设置了全新的 Ubuntu 安装并遵循了 this guide安装 RVM、Ruby 1.9.2 和 Rails 3。

然后我安装了 RubyMine 3.0，它自动从 RVM 路径中检测到 Ruby 1.9.2 SDK，这样就可以了。我可以完美地启动服务器(绿色播放按钮)。

现在的问题是我无法调试它，因为它在启动后会抛出以下异常。

我在 .Gemfile 中有以下行

gem 'ruby-debug19', :require => 'ruby-debug'

另外(根据一些博客)我安装了 ruby​​-debug-ide gem，如下所示:

gem install ruby-debug-ide19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-p180/

这绝对是一个 gem 相关的调试问题。不过，您不需要在 .gemfile 中包含调试 gem。 Rubymine 应该会自动拾取它，所以我会从那里删除它。

确保你已经为 1.9 安装了 debug-base gem

gem install ruby-debug-base19

我记得一开始有几个与 1.9 的一般调试相关的问题，但我认为它们现在已经解决了。

你看过这篇文章了吗？它还可以帮助您指明方向。
