angular - Angular 材质扩展面板错误 - TypeError: this.driver.containsElement is not a function

问题描述

Angular 材质的扩展面板依赖于 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，它会因错误而崩溃：

错误类型错误：this.driver.containsElement 不是 TransitionAnimationEngine.push../node_modules/@angular/animations/fesm5/browser.js.TransitionAnimationEngine._balanceNamespaceList (browser.js:2765) 处的函数 TransitionAnimationEngine.push../node_modules /@angular/animations/fesm5/browser.js.TransitionAnimationEngine.createNamespace (browser.js:2743) 在 TransitionAnimationEngine.push../node_modules/@angular/animations/fesm5/browser.js.TransitionAnimationEngine.register (browser.js: 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/ Animations.js.AnimationRendererFactory.createRenderer (animations.js:140) 在 DebugRendererFactory2.push../node_modules/@angular/core/fesm5/core.js.DebugRendererFactory2.createRenderer (core.js:12225) at createComponentView (core.js:11179) at callWithDebugContext (core.js:12204) at Object.debugCreateComponentView [as createComponentView] (core.js:11715) 在 createViewNodes (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，这是一个使用 @angular/material 、 @angular/cdk 和 @angular/animations 安装的简单 Angular 6 应用程序

Angular 和包版本：

Angular CLI：6.0.7 节点：8.9.3 操作系统：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 打字稿 2.7.2 webpack 4.8.3

解决方案

该版本的动画包似乎存在错误。进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，请对有问题的软件包进行完整更新：

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