You have to import those modules into your module where the current component is located via adding a reference to then into imports array.

@NgModule({
  ...
  imports: [
    BrowserModule,
    FormsModule, <====
    ReactiveFormsModule <====
  ],
  ...
});

Recompile the project, it should work now. Note that just adding the import this way: import { FormsModule, ReactiveFormsModule } from '@angular/forms' won't solve your problem because the module does not know about them, therefore FormsModule and ReactiveFormsModule won't be inserted into your bundle after compilation.
