[angular] 각도 오류 : ” ‘ngModel’은 (는) ‘입력’의 알려진 속성이 아니기 때문에 바인딩 할 수 없습니다”

정답입니다. FormsMoudle을 가져와야합니다.

app.module.ts에서 첫 번째

**

import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { NgModule  } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    FormsModule,
    ReactiveFormsModule ,
    BrowserModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

** app.component.spec.ts에서 두 번째

import { TestBed, async } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { AppComponent } from './app.component';
import { FormsModule } from '@angular/forms';
describe('AppComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [
        RouterTestingModule,
        FormsModule
      ],
      declarations: [
        AppComponent
      ],
    }).compileComponents();
  }));

안부와 희망이 도움이 될 것입니다

import { FormsModule } from '@angular/forms';

@NgModule({

   imports: [ FormsModule ],       // HERE

   declarations: [ AppComponent ],
   bootstrap: [ AppComponent ]
 })

beforeEach(async(() => {
  TestBed.configureTestingModule({
    imports: [
      FormsModule
    ],
    declarations: [
      RegisterComponent
    ]
  })
  .compileComponents();
}));

import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({
    declarations: [AppComponent],
    imports: [FormsModule],
})
