Error:
node_modules/@angular/common/http/http.d.ts:81:22 - error NG6002: Appears in
the NgModule.imports of AppModule, but could not be resolved to an NgModule
class.
This likely means that the library
(@angular/common/http) which declares HttpClient has not been processed
correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer
version of the library is available, and update if so. Also consider checking
with the library's authors to see if the library is expected to be compatible
with Ivy.

Problem
In app.modules.ts
|
import { HttpClient } from '@angular/common/http';
and
imports: [
BrowserModule,
HttpClient,
|
Solution:
Use HttpClientModule
in app.modules.ts
|
import { HttpClientModule } from '@angular/common/http';
|
And
|
imports: [
BrowserModule,
HttpClientModule,
|
AND stop
ng serve with ctrl+c and clean the npm serve cache in powershell Terminal and
start it again
|
Ctrl+c
npm cache clean –force
ng
serve
|
App.module.tsàError

import { HttpClient } from '@angular/common/http';
import { BehaviorSubject } from 'rxjs';
@NgModule({
declarations: [
AppComponent,
NavbarComponent,
ListTimeRecordsComponent
],
imports: [
BrowserModule,
AppRoutingModule,
HttpClient,
BehaviorSubject
],

Lösung
Man muss anstatt httpClient das
HttpClientModule in app.modules.ts installieren und ng serve stoppen
und erneut starten oder sogar npm cache clean --force
Ok:
app.modules.ts
|
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { TimerecordsService } from "./services/timerecords.service";
import { AppRoutingModule } from './app-routing.module';
//import { HttpClient } from '@angular/common/http';
import { HttpClientModule } from '@angular/common/http';
import { BehaviorSubject } from 'rxjs';
import { AppComponent } from './app.component';
import { NavbarComponent } from './components/navbar/navbar.component';
import { ListTimeRecordsComponent } from './components/list-time-records/list-time-records.component';
@NgModule({
declarations: [
AppComponent,
NavbarComponent,
ListTimeRecordsComponent
],
imports: [
BrowserModule,
HttpClientModule,
AppRoutingModule,
BehaviorSubject
],
providers: [TimerecordsService],
bootstrap: [AppComponent]
})
export class AppModule { }
