Erro! Can't bind to 'ngForOf' since it isn't a known property of 'ap-photo'

Estou seguindo o código do capítulo 4 da aula 2 porém encontro o seguinte erro com a diretiva ngFor:

compiler.js:1021 Uncaught Error: Template parse errors: Can't bind to 'ngForOf' since it isn't a known property of 'ap-photo'.

  1. If 'ap-photo' is an Angular component and it has 'ngForOf' input, then verify that it is part of this module.
  2. If 'ap-photo' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
  3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("ngfor vai pegar o objteo photos criado no app.com.ts e guarda na variavel photo --> <ap-photo [ERROR ->]*ngFor="let photo of photos" [url]="photo.url" [description]="photo.description"> "): ng:///PhotosModule/PhotoListComponent.html@2:4 Property binding ngForOf not used by any directive on an embedded template.
