TypeScript-'s Angular Framework Error - “There is no directive with exportAs set to ngForm”

Question

I keep getting this error while using TypeScript\'s Angular2-forms framework:

There is no directive with \"exportAs\" set to \"ngForm

Answer 1

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

imports:[
    BrowserModule.withServerTransition({ appId: 'ng-cli-universal' }),
    HttpClientModule,
    FormsModule,
    ReactiveFormsModule/*This one in particular*/,...
],

in app.module.ts to permanently solve errors like "cannot bind [formGroup] or no directive with export as".
