角度材质扩展面板错误 - TypeError:this.driver.containsElement不是函数

Question

Angular材质的扩展面板取决于BrowserAnimationsModule.我已经包含了动画模块,但是当我创建一个简单的扩展面板时,它崩溃并出现错误:

错误TypeError:this.driver.containsElement不是TransitionAnimationEngine.push ../ node_modules上TransitionAnimationEngine.push ../ node_modules/@angular/animations/fesm5/browser.js.TransitionAnimationEngine._balanceNamespaceList( browser.js:2765)的函数.在TransitionAnimationEngine.push ../node_modules/@angular/animations/fesm5/browser.js.TransitionAnimationEngine.register(browser.js:/@angular/animations/fesm5/browser.js.TransitionAnimationEngine.createNamespace( browser.js:2743) 2784)在InjectableAnimationEngine.push ../ node_modules/@angular/animations/fesm5/browser.js.AnimationEngine.register(browser.js:3815),在AnimationRendererFactory.push ../ node_modules/@ angular/platform-b​​rowser/fesm5/createComponentView(core.js)上的DebugRendererFactory2.push ../ node_modules/@angular/core/fesm5/core.js.DebugRendererFactory2.createRenderer(core.js:12225)的animations.js.AnimationRendererFactory.createRenderer(animations.js:140) :11179)在Object.de的callWithDebugContext(core.js:12204)createViewNodes上的bugCreateComponentView [as createComponentView](core.js:11715)(core.js:11220)

home.component.html

<div class="container-fluid">
    <div id="sidebar">
        <mat-expansion-panel>
            <mat-expansion-panel-header>
              <mat-panel-title>
                This is the expansion title
              </mat-panel-title>
              <mat-panel-description>
                This is a summary of the content
              </mat-panel-description>
            </mat-expansion-panel-header>
            <p>This is the primary content of the panel.</p>
          </mat-expansion-panel>
    </div>
    <div id="map" style="height: 550px"></div>
</div>

home.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { TranslateModule } from '@ngx-translate/core';

import { CoreModule } from '@app/core';
import { SharedModule } from '@app/shared';
import { HomeRoutingModule } from './home-routing.module';
import { HomeComponent } from './home.component';
import { QuoteService } from './quote.service';
import { LeafletModule } from '@asymmetrik/ngx-leaflet';
import { MatExpansionModule } from '@angular/material/expansion'

@NgModule({
  imports: [
    CommonModule,
    TranslateModule,
    CoreModule,
    SharedModule,
    HomeRoutingModule,
    LeafletModule,
    MatExpansionModule
  ],
  declarations: [
    HomeComponent
  ],
  providers: [
    QuoteService
  ]
})
export class HomeModule { }

请注意,这是一个安装了@ angular/material,@ angular/cdk和@ angular/animations的简单Angular 6应用程序

角度和包版本:

Angular CLI:6.0.7节点:8.9.3 OS:win32 x64 Angular:6.0.3

@ angular-devkit/architect 0.6.7 @ angular-devkit/build-angular 0.6.7 @ angular-devkit/build-optimizer 0.6.7 @ angular-devkit/core 0.6.7 @ angular-devkit/schematics 0.6.7 @角度/动画6.0.6 @ angular/cdk 6.3.1 @ angular/cli 6.0.7 @ angular/material 6.3.1 @ ngtools/webpack 6.0.7 @ schematics/angular 0.6.7 @ schematics/update 0.6.7 rxjs 6.2 .0 typescript 2.7.2 webpack 4.8.3

Answer 1

这个版本的动画包似乎有一个错误.执行临时修复并回滚到6.0.5.它将解决您的问题,如此stackblitz所示(您的动画版本会引发错误).

npm install --save @angular/animations@6.0.5

如果这不能解决问题,请对相关软件包进行全面更新:

$ ng update @angular/cli
$ ng update @angular/core
$ ng update @angular/material
