使用Ruby2 x64安装gem

Question

我正在尝试安装Rails，但是在需要正确安装devkit之前。
因此，我正在执行正常程序，但我不知道出了什么问题。 我正在使用ruby 2 x64，并尝试使用DevKit x32和x64。 这是与devkit x64一起使用的。 这里有什么问题吗？ 谢谢。

注意：在x32和x64情况下，在使用“ ruby​​ dk.rb install -f”进行安装之前。

编辑：对于谁试图回答有关ruby dk.rb等程序，我做了多次：

c：\\ DevKit>红宝石dk.rb初始化
初始化完成！ 请查看并修改自动生成的“ config.yml”文件，以确保它包含您要由DevKit增强的所有已安装红宝石的根目录。

c：\\ DevKit> ruby​​ dk.rb评估
根据运行“ ruby​​ dk.rb init”生成的“ config.yml”文件中的设置以及您的任何自定义，当您运行“ ruby​​ dk.rb install”时，DevKit功能将注入到以下Ruby中。

C：/ Ruby200-x64

c：\\ DevKit>红宝石dk.rb安装-f

请检查开发套件是否正确安装
