Question

我在浏览器上启动Angular应用程序时出现问题。一切都是代码说话，但我仍然收到这个错误：

找到合成属性@routerAnimations。请包括您的“BrowserAnimationsModule”或“NoopAnimationsModule” 应用

我已经检查了这个主题的帖子，并且有很多，但所有人都回答了同样的问题：

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

并将其包含在app模块的导入中。

imports: [
    BrowserAnimationsModule,
    ... 
]

这就是我所做的但仍然有同样的错误。我一直在寻找这个解决方案的好几个小时。谁知道什么可以解决它？感谢

这是我的package.json：

Answer 1

有一点绝对是您需要在活动模块中添加BrowsersAnimationModule。但是除此之外，您需要为该合成选择器（此处为animations）提及@routerAnimations，它是Angular Component Meta

@Component({
  selector: 'app-card-grid',
  templateUrl: './card-grid.component.html',
  styleUrls: ['./card-grid.component.scss'],
  animations: [
    trigger('routerAnimations', [
      state('collapsed', style({ height: '0px', minHeight: '0' })),
      state('expanded', style({ height: '*' })),
      transition('expanded <=> collapsed', animate('225ms cubic-bezier(0.4, 0.0, 0.2, 1)')),
    ]),
  ],

如果仍有疑问，请回复评论

Answer 2

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

和

imports: [
    BrowserAnimationsModule,
    ... 
]

实际上可以解决

Answer 3

我解决了这个问题，问题是app.component.html中的“@routerAnimations”：

<div [@routerAnimations]="myOutlet.state">
    <router-outlet #myOutlet></router-outlet>
</div>

当我删除它时，一切正常
