angular - 使用 ng 闪电遇到的角度错误

Question

我正在尝试使用 Angular 12 开始使用 ng 闪电框架按照以下链接中的步骤进行操作

https://ng-lightning.github.io/ng-lightning/#/get-started

使用以下安装 ng 闪电

npm install --save ng-lightning

还安装了@angular/cdk

npm install --save @angular/cdk

我的 app.module.ts 如下，添加了 'NglModule'

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import {NglModule} from 'ng-lightning';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
     NglModule,
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.html 如下

<button type="button" nglButton variant="brand">brand</button>



<ngl-combobox label="Make a choice" [options]="options" [(open)]="open" [(selection)]="selection">
  <input nglCombobox placeholder="Select an Option">
</ngl-combobox>

ts文件如下

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'demo-app2';
  options = ['One', 'Two', 'Three'];

  selection: string = "";

  open = false;
}

当我使用 ng serve 运行时，出现此错误

PS C:\SudhirLearning\Angular\projects\demo-app2> ng serve
