Can't bind to 'ngModelOptions' since it isn't a known property of 'input' in Angular 6

问题

Here is my HTML:

<nz-form-item nzFlex [formGroup]="hulkForm">
   <nz-form-label [nzSpan]="7" [nzFor]="hulkColumn.column" 
        [nzRequired]="hulkColumn.require">{{hulkColumn.lable}}</nz-form-label>
   <nz-form-control [nzSpan]="17">
   <input nz-input 
       placeholder={{hulkColumn.placeholder}} 
       [formControlName]="hulkColumn.name"
       [(ngModel)]="hulkColumn.model"
     [ngModelOptions]="{updateOn: 'blur'}"
     name="{{hulkColumn.name}}"
        *ngIf="hulkColumn.type!=='number'"
       >
 </nz-form-control>
</nz-form-item>

Here is the error in Chrome:

Here is app.module.ts:

import {BrowserModule} from '@angular/platform-browser';
import {NgModule} from '@angular/core';
import {HashLocationStrategy, LocationStrategy} from '@angular/common';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
import {HttpClientModule} from '@angular/common/http';
import {NgZorroAntdModule, NZ_I18N, zh_CN} from 'ng-zorro-antd';
import {registerLocaleData} from '@angular/common';
import zh from '@angular/common/locales/zh';

import {AppRoutingModule} from './app-routing.module';
import {AppComponent} from './app.component';


registerLocaleData(zh);

@NgModule({
  declarations: [
  AppComponent,
  ...
  ],
  imports: [
  ...
  FormsModule,
  ReactiveFormsModule,
  ...
  ],
  providers: [{provide: NZ_I18N, useValue: zh_CN}, {provide: LocationStrategy, useClass: HashLocationStrategy}, CheckLoginGuard],
  bootstrap: [AppComponent]
})

I'm using the following:

Angular CLI: 6.2.4
Node: 8.9.0
OS: darwin x64
Angular: 6.0.7

You need to import FormsModule in app.component.ts file

Steps:

Open app.module.ts

Add the following import statement

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

Add FormsModule in imports @NgModule

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

Final code:

app.component.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms'; //----<<< Adding Import Statement
import { AppComponent } from './app.component';

@NgModule({
 declarations: [
  AppComponent
 ],
 imports: [
  BrowserModule, 
  FormsModule //-------<< Import here
 ],
 providers: [],
 bootstrap: [AppComponent]
})

export class AppModule { }

回答2:

You missed to import the CommonModule of angular which provides ngmodel related structural directives.

Updating the above answer:

You are mixing the reactive forms and template forms. Please remove [formControlName] property as we cannot use FormsModule and ReactiveForms together

if you remove the above it works fine. You can see the below stackblitz https://stackblitz.com/edit/ng-zorro-antd-setup-juf9hp

回答3:

You have to also import ReactiveFormsModule.

That will work.

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