我正在尝试让 Jekyll 和 bower 在 Windows 8 中工作
我已经成功安装了 Ruby 和 DevKit，我尝试过，版本 2.0.2、1.9.3，然后再次使用来自http://railsinstaller.org/的 Rails 安装程序
我在下面遵循了场景 A 和 B，https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-gems_fails_comspec_autorun但都与我无关，
COMSPEC 是我的 cmd.exe 位置，我没有自动运行？
我可以运行gem install mysql，但尝试执行任一 rdiscount 都会给出以下结果
c:\devkit>gem install rdiscount
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing rdiscount:

我也尝试过重新安装/更新 gem，但我所遵循的一切似乎都不起作用？
谁能想到我可以尝试的其他方法？或将我指向可以提供帮助的地方。
这是我对 Ruby 的第一次尝试，我运气不佳。
谢谢肖恩
