npm 安装依赖 报这个错时： gyp: No Xcode or CLT version detected!
今天接盘一个公司的项目，因为疫情原因，公司发不出工资，很多人都离开了，而我被迫留守，所以要接手离职同事的项目。
废话不多说，进入主题。
当我开心的拉完项目，准备装好依赖开始一顿debug操作时，发现.. 项目跑不动，报错说缺了node-sass模块，好吧，那就install一下，结果没装成功，基本可以确定是这个绊脚石害我跑不起来项目了。接着，先品一品报错内容，报错如下：

最后选择重装xcode-select,因为xcode好几个g呢，下载完都天亮了。
注意事项：
要删了本地的xcode-select相关文件，一开始以为可以直接装，覆盖了，但是装不了，删了之后就可以了。
sudo rm -rf $(xcode-select -print-path)然后再安装之
sudo xcode-select --install装完之后再安装你想安装的依赖/模块,就可以啦！
最后吐槽下，sass这个老东西，发现接手的这个项目用的包，技术都不是我喜欢的简洁，快速方便。less就很香啊，不需要依赖ruby，直接装就好了，害我装这么多东西。只能说一下旧的历史遗留下来的东西好用但是麻烦，毕竟是过去的
