【问题描述】：
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gem install buildr 时，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:

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.
Provided configuration options:

--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib

【问题讨论】：
-
能否请您发布 mkmf.log？
-
您在使用
RubyInstaller二进制文件吗？ -
我建议将 Buildr 与 JRuby 一起使用。这大大减轻了痛苦，因为您唯一的依赖是 Java，通常在您使用 Buildr 构建 Java 项目时可用，并且您可以避免使用 ruby-java 桥。
