Ruby 在windows中使用中间人

我正在尝试在windows 8.1中安装middleman。我基本上遵循了这个帖子：

我运行了可执行文件

rubynstaller-2.0.0-p481.exe

。我在

C:\Ruby200

安装了它。然后我安装了devkit（

devkit-mingw64-32-4.7.2-20130224-1151-sfx.exe

）。我在

C:\Ruby200\devkit

提取了它。我打开一个终端，转到

C:\Ruby200\devkit

。运行命令

ruby dk.rb init

，然后运行

ruby dk.rb install

。一切如期进行。然后我用命令安装了middleman 3.1.5版：

gem install middleman-v3.1.5

。它返回时没有任何错误消息。然后我转到

C:\Users\a-user\a-project

并运行

middleman init a-site

。它显示了一条错误消息：

在此计算机上可用的gems中找不到gem“wdm（~>0.1.0）x86-mingw32”。运行bundle安装以安装缺少的gems

所以我运行了

捆绑安装
。它安装了许多gems，但最后出现了一条错误消息：

我认为我不需要kgio，但我不知道如何使
捆绑安装
摆脱它

我还尝试了最新的ruby、devkit和middleman版本，但也失败了。我也试过其他版本。所有这些最终都会在一些与本机扩展相关的方面失败。
getaddrinfo required似乎暗示kgio在某种程度上不是windows友好的？也许作者需要这个？这里也是一样
