Can't bind to 'ngForOf' since it isn't a known property of 'tr' (final release)

Add BrowserModule to imports: [] in @NgModule() if it's the root module (AppModule), otherwise the CommonModule.

// older Angular versions
// import {BrowserModule, CommonModule} from '@angular/common';

import { BrowserModule } from '@angular/platform-browser'
..
..
@NgModule({
  imports: [BrowserModule, /* or CommonModule */],
  ..
})

In my case, the issue was that my teammate mentioned *ngfor in templates instead of *ngFor. Strange that there is no correct error to handle this issue (In Angular 4).

You have to import 'CommonModule' in the module where you are using these in-built directives like ngFor,ngIf etc.

import { CommonModule } from "@angular/common";


@NgModule({
  imports: [
    CommonModule
  ]
})

export class ProductModule { }
