  • Hi, there are a lot of reason for this problem. Start by taking a look here https://github.com/angular/angular-cli/issues/4551 and then check your dependencies. – Karbos 538 May 02 '17 at 07:45
  • `@Inject(ProgramService) private programService: ProgramService, @Inject(CacheService) private cacheService: CacheService,` Does this work for you ? – Parth Ghiya May 03 '17 at 08:04

You will have to add @Inject so that its dependency can be resolved.

So for custom services inside your service Inject its dependency with @Inject

In your code replace your custom services with 

@Inject(ProgramService) private programService: ProgramService, @Inject(CacheService) private cacheService: CacheService,

You can understand it deeply from this blog. https://blog.thoughtram.io/angular/2015/09/17/resolve-service-dependencies-in-angular-2.html

  • Thank for your answer. For the ProgramService and CacheService can be resolved. but other array parameter cannot be resovled. – Jason.chen May 04 '17 at 02:34
  • Remove @Inject(Array) for those. – Parth Ghiya May 04 '17 at 02:41
  • @ParhGhiya, Thanks for your support, I have resolved that. Since the generic type parameter is not supported in Angular.Link https://github.com/rangle/angular-2-aot-sandbox#service-with-generic-type-param-top – Jason.chen May 05 '17 at 02:03
