Getting this error "Cannot import "import {FormGroup, FormControl} from '@angular/forms'" after adding angular Reactive form

I want to build a Reactive Form for a simple signup component in Angular. I am trying to import {FormGroup, FormControl} from '@angular/forms' but getting this error. Though I imported {FormsModule, ReactiveFormsModule} in app.module

Error :

Solution

  • The error is thrown if you're using the ReactiveFormsModule and an <form> element without a FormGroup ie you need to use a form after binding like, [formGroup]="myForm".
