Angular 导入“角度材质”对话框时出现编译错误

我试图在我的应用程序中显示一个模型对话框。作为第一步，我导入了“材质”对话框 进入我的component.ts文件

从'@angular/material/dialog'导入{MatDialog}；

但是在导入之后，我得到了类似这样的编译错误提示

我对这些错误一无所知。我是个新手。仅删除导入行时，所有错误都将消失。。成功编译

将角度/材质版本从降级到LTS 11.2.3应该可以解决此问题。

在我的情况下，这是因为我正在使用过时的角度cli打开一个新项目，

npm i@angular/cli@latest

并再次创建该项目将其修复。

ng update@angular/cli@angular/core

可能吗？核心是11.x，材料是12。x@Sandeep可能将
