Angular4：PrimeNG不行

Question

我尝试PrimeNG在我的项目angular4整合，我跟着网站的设置，但是当我导入一个模块，它会显示错误消息，例如：

Can't bind to 'ngModel' since it isn't a known property of 'p-inputSwitch'. 

home.module。 TS

import { NgModule } from '@angular/core'; 
import { ChartsModule } from 'ng2-charts/ng2-charts'; 
import { BsDropdownModule } from 'ngx-bootstrap/dropdown'; 

import { HomeComponent } from './home.component'; 
import { HomeRoutingModule } from './home-routing.module'; 
import {InputSwitchModule} from 'primeng/primeng'; 

@NgModule({ 
    imports: [ 
    HomeRoutingModule, 
    ChartsModule, 
    BsDropdownModule, 
    InputSwitchModule 
    ], 
    declarations: [ HomeComponent ] 
}) 
export class HomeModule { } 

home.component.ts

import { Component, OnInit } from '@angular/core'; 
import { Router } from '@angular/router'; 

@Component({ 
    templateUrl: 'home.component.html' 
}) 
export class HomeComponent implements OnInit { 

    // constructor() { } 
    checked1: boolean = false; 
    checked2: boolean = true; 
/
. 
. 
. 
/
} 

home.component.html

<h3 class="first">Basic - {{checked1}}</h3> 
<p-inputSwitch [(ngModel)]="checked1"></p-inputSwitch> 

<h3>Labels - <span> {{checked2}}</span></h3> 
<p-inputSwitch onLabel="Yes" offLabel="No" [(ngModel)]="checked2"></p-inputSwitch> 

Answer 1

如果您未导入“FormModule”，您将看到此消息。 对于你的情况，我没有看到这个地方。

Can't bind to 'ngModel' since it isn't a known property of X. 

此消息表明无法找到'ngModel'声明。
