Angular error: "Can't bind to 'ngModel' since it isn't a known property of 'input'"

In order to use two-way data binding for form inputs you need to import the FormsModule package in your Angular module.

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

@NgModule({
    imports: [
         FormsModule      
    ]

EDIT

Since there are lot of duplicate questions with the same problem, I am enhancing this answer.

There are two possible reasons

• Missing FormsModule, hence Add this to your Module,

  import { FormsModule } from '@angular/forms';
  
  @NgModule({
      imports: [
          FormsModule      
      ]
  

• Check the syntax/spelling of [(ngModel)] in the input tag
