Answer 1

您需要在导入中包含MatDialog模块。

import {MatDialogModule} from '@angular/material';
@NgModule({
   imports :[MatDialogModule],
   ...
})

Answer 2

从“ @ angular / material / dialog”导入{MatDialogModule}导入对话框； 通过将以下代码添加到module.ts文件中

import {MatDialogModule} from '@angular/material/dialog';

然后将其导入到导入中，如下所示，

const MaterialComponent = [MatDialogModule];
