ruby和gem rdiscount windows 8 64bit的安装问题

Question

我试图让Jekyll和bower在Windows 8中工作

我已经设法安装了Ruby，我尝试了DevKit，版本2.0.2,1.9.3，然后再使用http://railsinstaller.org/上的Rails安装程序

我已经按照下面的方案A和B进行了操作， https：//github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-gems_fails_comspec_autorun但两者都不相关，

COMSPEC是我的cmd.exe位置，我没有自动运行？

我可以运行gem install mysql但是试图做rdiscount给出以下内容

c:\devkit>gem install rdiscount
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing rdiscount:

如果我运行gem install jekyll我会收到以下错误

我也尝试重新安装/更新gem，但我没有注意到它似乎工作？

谁能想到我能尝试的其他事情？ 或者指出我可以提供帮助的地方。

这是我第一次尝试使用Ruby而且运气不好。

谢谢肖恩

Answer 1

此问题已通过rdiscount 2.0.7.2修复

gem install rdiscount -v 2.0.7.2

Answer 2

问题不是Ruby，RubyInstaller或DevKit，而是在Windows上破坏了RDiscount gem，请参阅报告的问题＃74 。

您可以安装旧版本的RDiscount，例如1.6.x：

gem install rdiscount -v 1.6.8
