我正在尝试安装一些依赖项以在 Windows 7 上构建项目。我已经安装了 Cygwin 以及我认为需要的 Ruby 依赖项。

当我运行时，gem install buildr我收到以下错误。有什么建议么？

$ gem install buildr
Building native extensions.  This could take a while...
ERROR:  Error installing buildr:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

仅 Windows 上的 JRuby 支持 Buildr。您可以在 Windows 上安装 rjb，但这是一个痛苦的过程。JRuby 非常快（在 JDK7 上甚至更快，对团队表示敬意），这样你可能会很好。
