gem install buildr失败

我试图在Windows 7上安装一些项目的依赖关系。我已经安装了Cygwin和我认为我需要的Ruby依赖关系。gem install buildr失败

当我运行gem install buildr时收到以下错误。有什么建议么？

$ gem install buildr 
Building native extensions. This could take a while...

您可以发布mkmf.log吗？ – sunnyrjuneja

你在使用'RubyInstaller'二进制文件吗？ – Azolo

我建议使用Buildr和JRuby。这可以减轻很多痛苦，因为你唯一的依赖是Java，当你使用Buildr构建Java项目时通常可以使用Java，并且你可以避免使用ruby-java桥。 – vanto

Buildr仅在Windows上支持JRuby。你可以在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，对团队来说更是如此），而且你可能会很好。
