NullInjectorError: No provider for NgbModalRef

Question

I try to use NgbModalRef to close a Modal (That open with NgbModal) and in some components I see the Error:

ERROR Error: Uncaught (in promise): NullInjectorError: R3InjectorError(MyModule)[NgbModalRef -> NgbModalRef -> NgbModalRef -> NgbModalRef -> NgbModalRef]: NullInjectorError: No provider for NgbModalRef!

---

Note1:I have imported and Injected NgbModalRef and NgbModal in my component and tried using NgbModule in my appModule and it didnt Work! Note2:I saw somewhere that people say to write NgbModalRef in appModule provider,and i dont think its the right way because its not a Service!! Can anyone please help..
