Question

我正在尝试安装rails，但在我需要正确安装devkit之前所以我正在做正常的程序，但我不明白什么是错的。我正在使用ruby 2 x64，我尝试使用DevKit x32和x64。这是与devkit x64。这里有什么不对......？谢谢。

注意：在x32和x64两种情况下安装“ruby dk.rb install -f”之前。

编辑：对于谁试图回复关于ruby dk.rb等程序，我已多次这样做了：

c：\ DevKit＆gt; ruby dk.rb init
初始化完成！请查看并修改自动生成的内容 'config.yml'文件，以确保它包含所有的根目录您想要通过DevKit增强安装的Rubies。

c：\ DevKit＆gt; ruby dk.rb review
根据生成的'config.yml'文件中的设置从运行'ruby dk.rb init'和任何自定义项， DevKit功能将注入以下Rubies 当你运行'ruby dk.rb install'时。

C：/ Ruby200-64

c：\ DevKit＆gt; ruby dk.rb install -f
