angular - 如何修复错误类型错误 : Class constructor HammerGestureConfig cannot be invoked without 'new'

Question

我在添加 ngx-gallery 时遇到问题。检查时出现错误错误类型错误:类构造函数 HammerGestureConfig 不能在没有“new”的情况下被调用

我已经在app.module中添加了hammerjs但是还是有问题

这是我的 app.module

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { FormsModule } from '@angular/forms';
import { BsDropdownModule, TabsModule } from 'ngx-bootstrap';
import { RouterModule } from '@angular/router';
import { appRoutes } from './routes';
import { AuthGuard } from './_guards/auth.guard';
import { AuthService } from './_services/auth.service';
import { ErrorInterceptorProvider } from './_services/error.interceptor';
import { AlertifyService } from './_services/alertify.service';
import { UserService } from './_services/user.service';
import { JwtModule } from '@auth0/angular-jwt';
import { MemberDetailResolver } from './_resolvers/member-detail.resolver';
import { MemberListResolver } from './_resolvers/member-list.resolver';
import { NgxGalleryModule } from 'ngx-gallery';


import { AppComponent } from './app.component';
import { NavComponent } from './nav/nav.component';
import { DashboardComponent } from './dashboard/dashboard.component';
import { RegisterComponent } from './register/register.component';
import { MemberListComponent } from './members/member-list/member-list.component';
import { ListComponent } from './list/list.component';
import { MessagesComponent } from './messages/messages.component';
import { MemberCardComponent } from './members/member-card/member-card.component';
import { MemberDetailComponent } from './members/member-detail/member-detail.component';

export function tokeGetter() {
  return localStorage.getItem('token');
}

@NgModule({
  declarations: [
    AppComponent,
    NavComponent,
    DashboardComponent,
    RegisterComponent,
    MemberListComponent,
    ListComponent,
    MessagesComponent,
    MemberCardComponent,
    MemberDetailComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule,
    FormsModule,
    BsDropdownModule.forRoot(),
    TabsModule.forRoot(),
    RouterModule.forRoot(appRoutes),
    NgxGalleryModule,
    JwtModule.forRoot({
      config: {
        tokenGetter: tokeGetter,
        whitelistedDomains: ['192.168.100.6:5000'],
        blacklistedRoutes: ['192.168.100.6:5000/api/auth']
      }
    })
  ],
  providers: [
    AuthService,
    ErrorInterceptorProvider,
    AlertifyService,
    AuthGuard,
    UserService,
    MemberDetailResolver,
    MemberListResolver
  ],

  bootstrap: [AppComponent]
})
export class AppModule { }

我想在每个用户中显示照片，但是因为错误不能显示

有更好的方法来解决这个问题。

修改 app.module.ts 中的提供者

export class CustomHammerConfig extends HammerGestureConfig  {
   overrides = {
       pinch: { enable: false },
       rotate: { enable: false }
   };
}

并添加到提供者

providers: [
    {
        provide: HAMMER_GESTURE_CONFIG, useClass: CustomHammerConfig 
    }
]
