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

I have encountered similar problem. I solved it by changing export order in the barrel.

Basic service files:

// dependency.service.ts
@Injectable()
export class DependencyService { }

// dependant.service.ts
import { DependencyService } from '.';

@Injectable()
export class DependantService {
    constructor(private dependency: DependencyService) { }
}

Following barrel causes the error:

// index.ts
export * from './dependant.service';
export * from './dependency.service';

While following one works:

// index.ts
export * from './dependency.service';
export * from './dependant.service';
