推荐答案

确保安装devkit(选中将更新路径的复选框): 您可能还需要重新安装Ruby.

Make sure you install the devkit (ticking the checkboxes that will update the path) : You might need to reinstall ruby too.

安装DevKit

从此处下载开发套件 http://rubyinstaller.org/downloads/

DevKit网址与Ruby 1.8.7和1.9.3一起使用:

DevKit url at this time For use with Ruby 1.8.7 and 1.9.3: DevKit-tdm-32-4.5.2

用于Ruby 2.0及更高版本(仅32位版本): DevKit-mingw64-32- 4.7.2

For use with Ruby 2.0 and above (32bits version only): DevKit-mingw64-32-4.7.2
