[英]ERROR in src/app/app.module.ts(15,15): error TS2304: Cannot find name 'ServiceName'
[英]ERROR in src/app/app.module.ts:38:5 - error TS2304: Cannot find name 'HttpClientModule'
我将 Angular-8 用于特定项目。
这是我的 app.module.ts
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { LoginModule } from './login/login.module';
import { CoreModule } from './core/core.module';
import { SharedModule } from './shared/shared.module';
import { ReactiveFormsModule } from '@angular/forms';
import { HTTP_INTERCEPTORS } from '@angular/common/http';
import { ErrorsModule } from './errors/errors.module';
import { RouterModule } from '@angular/router';
import { PagesModule } from './pages/pages.module';
import { FormsModule } from '@angular/forms';
import { SidebarComponent } from './shared/sidebar/sidebar.component';
import { StoreModule } from '@ngrx/store';
import { reducers, metaReducers } from './store/reducers';
import { StoreDevtoolsModule } from '@ngrx/store-devtools';
import { environment } from '../environments/environment';
import { EffectsModule } from '@ngrx/effects';
import { AppEffects } from './store/effects/app.effects';
import { JwtInterceptor } from './core/interceptors/jwt.interceptor';
import { ErrorInterceptor } from './core/interceptors/error.interceptor';
import { CacheInterceptor } from './core/interceptors/cache.interceptor';
import { ServiceWorkerModule } from '@angular/service-worker';
import { HttpClientTestingModule } from '@angular/common/http/testing';
import {HttpClientModule} from '@angular/common/http';
@NgModule({
imports: [
RouterModule,
BrowserModule,
BrowserAnimationsModule,
LoginModule,
CoreModule,
SharedModule,
ReactiveFormsModule,
HttpClientModule,
ErrorsModule,
PagesModule,
FormsModule,
AppRoutingModule,
StoreModule.forRoot(reducers, {
metaReducers,
runtimeChecks: {
strictStateImmutability: true,
strictActionImmutability: true
}
}),
!environment.production ? StoreDevtoolsModule.instrument() : [],
EffectsModule.forRoot([AppEffects]),
StoreDevtoolsModule.instrument({
maxAge: 25,
logOnly: environment.production
}),
ServiceWorkerModule.register('ngsw-worker.js', {
enabled: environment.production
})
],
当我做 ng 服务时,我收到了这个错误:
src/app/app.module.ts:38:5 中的错误 - 错误 TS2304:找不到名称“HttpClientModule”。
这是第 38 行:
HttpClient模块,
我该如何解决这个问题?
谢谢
Angular 4.3.0版本引入了HttpClient。 此外,您必须确保在主 AppModule 的导入元数据中导入并注入了 HttpClientModule。
// Import HttpClientModule from @angular/common/http in AppModule import {HttpClientModule} from '@angular/common/http'; //in place where you wanted to use `HttpClient` import { HttpClient } from '@angular/common/http';
