如果有上面的错误 或者 是win7 64bit (bug)

那么执行

Since it seems you have DevKit installed already, run this command

gem install ruby-debug-ide --platform=ruby --pre

As mentioned in that post, it's a bug fixed in not yet released version of ruby-debug-ide

Edit:

This seems to work (Windows 7 64 bit):

gem install ruby-debug-ide --pre

gem install ruby-debug-base19x --pre
