【问题描述】：
我正在尝试安装 ruby-debug。我使用的是 Mac OS 10.7.4、XCode 版本 2308 和 Ruby 版本 1.9.3-p194。
按照此处的说明：http://guides.rubyonrails.org/debugging_rails_applications.html#debugging-with-ruby-debug，我尝试运行
sudo gem install ruby-debug
我收到以下错误：
Building native extensions. This could take a while...
ERROR: Error installing ruby-debug:

所以我尝试了以下命令：
sudo gem install debugger
导致：
Fetching: columnize-0.3.6.gem (100%)

所以我研究了这个问题，最后发现了这个帖子：
how do I install ruby-debug in ruby 1.9.3 / Rails 3.2.1
在我尝试命令之前一切正常：
gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$SANDBOX/packages/ruby-1.9.3-p194
刚刚重现了上面的第一个错误。所以我研究了
rb_method_entry_t.called_id
发现了这个帖子：https://github.com/ruby/ruby/pull/56/#issuecomment-3463264
我尝试了他建议的步骤，除了 rehash（我不确定如何使用 rvm，并且不想切换到 rbenv 只是为了尝试它）。我将他推荐的所有 gem 下载到一个文件夹中，然后运行以下命令：
gem install *.gem -- --with-ruby-include=$(echo ~/.rvm/rubies/1.9.3-p194/include/ruby-1.9.1/ruby-1.9.3-p194/) --no-rdoc --no-ri
它很好地安装了 linecache19-0.5.13，但它在 ruby-debug-base19-0.11.26.gem 上阻塞，再次产生第一个错误。
我还尝试卸载运行 sudo gem install debugger 时添加的调试器 gem，但这并没有改变任何东西。
我不知道下一步该做什么。

一般来说，在使用rvm的时候不应该使用sudo，不过我觉得和你的问题没有关系。
