我不知道该如何去修复这个,因为我没有做太多在设置本地扩展方面有很多经验。任何帮助将不胜感激。让我知道是否需要提供更多信息。
错误日志指出您必须安装开发工具。尝试通过运行'xcode-select --install'来安装它们 - 希望有所帮助。 – Zoran
我试过了,我的所有工具都已安装。它的响应如下:'xcode-select:error:命令行工具已经安装,使用“软件更新”安装更新'。所以我跑了一个软件更新,重新启动并试图安装nokogiri。仍然收到完全相同的错误消息。 – Nappstir
你接受了许可协议吗?试试'sudo xcodebuild -license'或者只是打开xcode – amree
