Ruby 无法在windows 7 x64上安装github页面

我正在尝试在Github页面中使用Jekyll构建网站，在本地计算机Windows 7 x64企业版中安装Github Pages gem时遇到问题

以下是我采取的步骤： *在c:\Ruby21\（文件rubyinstaller-2.1.7.exe）上安装了32位ruby 2.1.7 *在c:\devkit\处安装了相应的devkit（文件devkit-mingw64-32-4.7.2-20130224-1151-sfx.exe） *运行“gem install json--platform=ruby”来安装RubyGems库json *确认JSON gem ok:ruby-rubygems-e“需要'JSON'；放置JSON.load（'[42]'）。检查，我得到了响应42

• 运行“gem安装bundler”，安装正常

• 我去了本地回购，创建了一个包含以下内容的文件：
  来源“” gem“github页面”

• 运行“bundle安装”

上次运行失败，出现以下消息：
