使用 Ruby2 x64 安装 gem

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。这是使用 devkit x64 的。这里有什么问题..？谢谢。

注意：在我在 x32 和 x64 情况下都使用“ruby dk.rb install -f”安装之前。

编辑：对于试图回复 ruby​​ dk.rb 等程序的人，我已经多次这样做了：

c:\DevKit>ruby 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，以确保它包含所有的根目录 您希望通过 DevKit 增强的已安装红宝石。
