使用Ruby2 x64安装gem

Question

我正在尝试安装rails，但在此之前我需要正确安装devkit
所以我正在做正常的手术，但我不明白出了什么问题。我使用的是ruby 2 x64，我尝试过使用DevKit x32和x64。这是与devkit x64。这里可能出了什么问题。。？非常感谢。

注意：在我使用"ruby dk.rb install-f"在x32和x64两种情况下安装之前。

编辑：对于谁试图回复关于ruby dk.rb等程序，我已经做了多次：

c： \DevKit>ruby dk.rb init
初始化完成！请查看并修改自动生成的"config.yml"文件，以确保它包含所有您想要通过DevKit增强的已安装Rubies。

c： \DevKit>ruby dk.rb评论
基于生成的"config.yml"文件中的设置通过运行"ruby dk.rb init"和任何自定义项，DevKit功能将注入以下Rubies当您运行"ruby dk.rb install"时。

C：/Ruby200-x64

c： \DevKit>ruby dk.rb install-f
