Question

我已经尝试在osx上安装指南针和ffi，但得到了同样的错误。我已经重新配置并重新安装了ruby，我已经安装了Xcode命令行工具，我已经重新启动了我的机器，似乎没有什么能够每次修复完全相同的错误。我要擦拭我的机器并重新开始，我不知道为什么在尝试安装宝石时我无法解决这个错误：

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby -r ./siteconf20160508-18749-v694wb.rb extconf.rb
checking for ffi.h... *** extconf.rb failed ***

由于某些原因无法创建Makefile，可能缺少必要的库和/或标题。检查mkmf.log文件以获取更多详细信息。你可以需要配置选项。

要查看此扩展无法编译的原因，请查看mkmf.log，可在此处找到：
