Angular2 - Error: Can't resolve all parameters for IconService

Question

I\'ve been trying to switch my app over to AoT compilation and have been getting this error in the production environment when the app is loading (it works fine locally).

Answer 1

My issue was that I was inheriting from a base class, and I had decorated that base class with @Injectable. The inheriting class was the class that should have the @Injectable attribute, not the base class. It seems that when the compiler sees the @Injectable attibute, it checks to make sure all the properties in the constructor can be injected. If not, it's an error. I solved it by removing the @Injectable attibute from that class.
