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

Question

I've got the following error when launching my Angular app, even if the component is not displayed.

I have to comment out the <input> so that my app works.

zone.js:461 Unhandled Promise rejection: Template parse errors: Can't bind to 'ngModel' since it isn't a known property of 'input'. ("    <div>       <label>Created:</label>       <input  type="text" [ERROR ->][(ngModel)]="test" placeholder="foo" />    </div> </div>"): InterventionDetails@4:28 ; Zone: <root> ; Task: Promise.then ; Value:  

I'm looking at the Hero plunker, but I don't see any difference from my code.

Here is the component file:

import { Component, EventEmitter, Input, OnInit, Output } from '@angular/core'; import { Intervention } from '../../model/intervention';  @Component({    selector: 'intervention-details',    templateUrl: 'app/intervention/details/intervention.details.html',    styleUrls: ['app/intervention/details/intervention.details.css'] })  export class InterventionDetails {    @Input() intervention: Intervention;     public test : string = "toto"; } 

Answer 1

Yes, that's it. In the app.module.ts file, I just added:

import { FormsModule } from '@angular/forms';  [...]  @NgModule({   imports: [     [...]     FormsModule   ],   [...] })
