推荐答案

您的@angular/material命令当前未安装所有依赖项，因此为什么抛出错误并尝试运行@angular/material @angular/cdk @angular/animations安装角材.

Your @angular/material command is not install all the dependency currently that why throw error try to run @angular/material @angular/cdk @angular/animations install angular material.

对于旧版本，请使用:-

For old version use:-

npm install — save @angular/material @angular/cdk @angular/animations

对于最新版本，请使用:-

For latest version use:-

ng add @angular/material
