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

I have this simple input in my component which uses [(ngModel)] :

<input type="text" [(ngModel)]="test" placeholder="foo" />

And I get the following error when I launch my app, even if the component is not displayed.

zone.js:461 Unhandled Promise rejection: Template parse errors:
Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input’.

Here is the component.ts:

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";
}

Solution

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

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

[...]

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