Question

我正在尝试安装一些依赖项来在Windows 7上构建项目。我已经安装了Cygwin，我认为我需要Ruby依赖项。

当我运行gem install buildr时，收到以下错误消息。有什么建议？

$ 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

只有Windows上的JRuby才支持Buildr。您可以在Windows上安装rjb，但这是一个痛苦的过程。 JRuby速度非常快（在JDK7上速度更快，对团队而言也是如此），你可能也会很好。

gem install buildr失败
