Windows 8上的Ruby DevKit仍然无法安装本机扩展

Question

我在Windows8-64bit上使用Ruby 1.9.3。 我的Ruby安装在C:\\Ruby193 ，Devkit在C:\\DevKit

我遵循了DevKit的安装方法，并获得了成功。

然后指南要求我通过运行gem install json --platform=ruby来测试它，它返回此错误（与安装DevKit之前的外观类似）：

注 ：此的其他问题在这里跟我到添加DevKit的安装文件夹到环境PATH ，我做到了，但仍然得到了同样的错误。

C:\Users\myname>gem install json --platform=ruby
Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

有什么办法吗？ 谢谢

Answer 1

抱歉，我使用了错误的DevKit。

对于Ruby 1.9.3及更低版本，我们应使用DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe mingw适用于2.0及更高版本。

现在效果很好。
