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

The problem in my case was missing component declaration in the module, but even after adding the declaration the error persisted. I had stop the server and rebuild the entire project in VS Code for the error to go away.
