最佳答案
该错误是由于macOS Mojave已停止将标准头文件放置在/usr/include
中,仅将它们保留在XCode目录中。
您可以通过运行ls /usr/include
进行验证,并且很可能该目录已不存在。相反,通过运行xcode-select --install
的通常技巧不会解决该问题。
修复程序是运行Apple提供的旧版安装程序,该程序会将头文件安装到/usr/include
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
关于macos - 升级到macOS之后,Mojave gem更新失败,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/52514791/
