This post shows you how to solve Can't bind to 'ngModel' since it isn't a known property of 'input' in Angular.

Uncaught Error: Template parse errors:
Can't bind to 'ngModel' since it isn't a known property of 'input'.

To solve the problem you should open the app.module.ts then import the FormsModule.

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

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

I hope so you can fix the problem Can't bind to 'ngModel' since it isn't a known property of 'input'.
