Answer 1

I solved my problem

the problem was because I use in a component so you need to add in components.modules.ts imports: [IonicModule],

that's all

Answer 2

You need to add this to components modules

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

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

Answer 3

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

Simply, import the above (FormsModule) module in your modules page it will work!
