'No provider' error (even though I've added a provider)

Question

I\'m trying to call a service from a particular class, but for some reason it can\'t be called, even though I am able to use it in other classes. I\'m using @Input

Answer 1

Exactly the same error message ("No provider for SomeService") can be triggered by having another service with the same name in your app. So it would look like you correctly included SomeService #1 in your module, added to the providers section, but it would still throw you the error. It puzzled me until I realized that there's SomeService #2 being imported in one of my components.
