我正在尝试关注https://material.angular.io/components/component/dialog上的文档,但我不明白为什么会有以下问题?
我在组件上添加了以下内容:
@Component({
selector: 'dialog-result-example-dialog',
templateUrl: './dialog-result-example-dialog.html',
})
export class DialogResultExampleDialog {
constructor(public dialogRef: MdDialogRef<DialogResultExampleDialog>) {}
}
在我的模块中,我添加了
import { HomeComponent,DialogResultExampleDialog } from './home/home.component';
@NgModule({
declarations: [
AppComponent,
LoginComponent,
DashboardComponent,
HomeComponent,
DialogResultExampleDialog
],
// ...
但是我得到这个错误。
EXCEPTION: Error in ./HomeComponent class HomeComponent - inline template:53:0 caused by: No component factory found for DialogResultExampleDialog. Did you add it to @NgModule.entryComponents?
