当我想安装 ruby-debug 和 ruby-debug-ide 时，我遇到了太多错误。
像这样的错误（捆绑安装）：
Using ruby_core_source (0.1.5)
Using linecache19 (0.5.13)
Using rails (3.2.5)
Using ref (1.0.0)

An error occurred while installing ruby-debug-base19 (0.11.24), and Bundler cannot continue.
Make sure that `gem install ruby-debug-base19 -v '0.11.24'` succeeds before bundling.
在相同的解决方案上：
gem install ruby-debug-base or ruby-debug-base19
同样的错误，
ERROR: Failed to build gem native extension.
有人知道该怎么做吗？
