我正在尝试使用Jekyll在Github Pages中构建网站，我在本地机器Windows 7 x64企业版中安装github-pages gem时出现问题。
以下是我采取的步骤： *在c：\ Ruby21 \安装ruby 2.1.7 32位（文件rubyinstaller-2.1.7.exe） *在c：\ Devkit \中安装了相应的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“require'json';放JSON.load（'[42]'）。inspect，我得到了回复42。
运行“gem install bundler”，安装好。
我去了本地仓库，创建了一个包含内容的Gemfile：
来源'https://rubygems.org' gem'github-pages'
上次运行失败，并显示以下消息：

An error occurred while installing rdiscount (2.1.7), and Bundler cannot
continue.
Make sure that `gem install rdiscount -v '2.1.7'` succeeds before bundling.

我没有c的背景。我不确定问题是什么以及如何解决它。
感谢任何帮助！
PS：
我尝试过不同的Ruby版本（2.1.7 / 2.2.3）和x86 / x64，都导致了同样的错误。我也试过另一台机器，win7终极和安装没有任何错误。我怀疑这个特定的win7 ent机器有一些特定的错误。
我跑的cmd是管理员权限。
答案 0 :(得分：2)
可能相关：您有一个64位操作系统，但使用的是32位Ruby。尝试使用64位Ruby（和DevKit）。
您也可以尝试在2.2位Windows上进行显式测试的Ruby 2.2.2。
