请试试这个：
ng 更新@angular/cli
npm 安装
最新版本的 Angular CLI (12.0.1) 不支持低于 12.20 版本的 Node。
解决方案
Update your version of Node to the latest stable version
- 您应该选择标记为 LTS 的版本，在撰写本文时该版本在 14.x.x 范围内。
解决方法
仅当您出于某种原因完全无法更新您的 Node 版本时才这样做
将 node-sass 添加到您的项目 devDependencies，直到您能够更新您的节点版本。
npm i -save-dev node-sass
yarn add -D node-sass
您应该谨慎使用此解决方法，因为 node-sass 即将被弃用。
