Angular 2 'component' is not a known element

Question

I\'m trying to use a component I created inside the AppModule in other modules. I get the following error though:

\"Uncaught (in promise): Error: Temp

Answer 1

I was facing the same issue. In my case I have forgotten to declare Parent component in the app.module.ts

As a example if you are using selector in ToDayComponent template, you should declare both ToDayComponent and DatepickerComponent in the app.module.ts
