ruby-on-rails - 无法使用 Ruby 1.9.3 在 RubyMine 4.5 中进行调试

Question

对于问题的长度，我深表歉意，但我想明确表示我没有犯任何愚蠢的错误!

因此，我正在努力使用 Ruby 1.9.3 在 RubyMine 4.5 中进行调试，我的步骤如下:

Ruby 1.9.3、Ruby Gems、DevKit 和 Rails(在 this guide 之后)的全新(即删除了所有以前的 ruby​​ 和 gem 目录)安装 - 工作正常。

然后我尝试开始使用我团队的 ruby​​ 代码。我在 RubyMine 中打开目录(记得先删除 .idea 目录)，系统提示我按要求(从控制台)运行 bundle install。这成功完成。重新启动 RubyMine。

然后我确保 Ruby 正常工作:Tools > IRB Console > puts "test" #test => nil - 有效我现在尝试调试器 (SHIFT + F9) 并查看消息:

当前未安装调试器所需的 gem ruby​​-debug-base19x。您要安装它吗？”

我点击取消并检查我的 Gemfile，目前唯一与调试相关的是:

# Debugging
gem 'debugger'
#gem 'ruby-debug-base19', :require => false
#gem 'ruby-debug19', :require => false
gem 'ruby-prof', :require => false #, :git => 'git://github.com/wycats/ruby-prof.git'

看起来我们有支持 ruby-debug 的调试器。读书here , 然而，似乎 debugger 是不够的。我需要安装 ruby-debug-base19x。所以，关注 SO ，我从 Gemfile 中注释掉调试器并运行

gem install ruby-debug-base19x --pre
gem install ruby-debug-ide --pre

运行良好，所以我添加

gem 'ruby-debug-base19x', '0.11.30.pre10'
gem 'ruby-debug-ide', '0.4.17.beta14'

到我的 Gemfile，然后从控制台运行 bundle install。

最后，我打开 RubyMine 中的调试器 (SHIFT + F9)。并且 puts "test"#test => nil 再次起作用。所以我尝试双击我的脚本的 gutter 来创建一个断点，RubyMine 暂停了一秒钟然后我得到:

我也尝试过使用代码的备份副本并按照相同的步骤操作，但在尝试加载调试器时我也遇到了以下错误:

脚本没有任何问题(我之前使用它很好)并且跟踪似乎与 ruby-debug-ide 有关 - 发生了什么？

感谢您的帮助 - 这让我抓狂!

更新:RubyMine 6+ 支持调试器 gem。

确保从您的 Gemfile 中删除 gem 'debugger'，这是一个已知的冲突，会中断 RubyMine 的调试。您只需要 2 个与调试器相关的 gem，正如我的 another answer 中所述链接在你的问题中。

删除 gem 后，您需要确保项目中的任何地方都没有引用它。在这种特殊情况下，r_spec_runner.rb 有 require 'ruby-debug' 语句导致 cannot load such file -- ruby​​-debug 尝试时出错运行 rails console。
