Error: (SystemJS) Can't resolve all parameters for ActivatedRoute: (?, ?, ?, ?, ?, ?, ?, ?)

I'm trying to inject ActivatedRoute component into my component to access the ID of the object I'm editing (or to find out, there's no ID param, new object is created).

I've created only the template for the component, and when I load start page (not event the page with the component I want to use) I get the following error:

Error: (SystemJS) Can't resolve all parameters for ActivatedRoute: (?, ?, ?, ?, ?, ?, ?, ?).

This is my code:

import { Component, OnInit } from '@angular/core';

import { ActivatedRoute} from "@angular/router";

@Component({
    selector: 'my-edit',
    templateUrl: './templates/my-edit.htm',
    providers: [ActivatedRoute]
})

export class MyEditComponent implements OnInit {

    constructor(private route : ActivatedRoute){
        console.log(route.params)
    }

    ngOnInit() : void {
    }

}

It's based on the code from example from AngularJS site (Heroes), and I really don't get where's the problem here... Can't I import ActivatedRoute into Component, or I need something extra to be able to import it?

My routing configuration is:

@NgModule({
  imports: [ RouterModule.forRoot(routes) ],
  exports: [ RouterModule ]
})
export class AppRoutingModule {}

where routes are the collection of routes, just like in angular example, and AppRoutingModule is imported in app.module.

Remove providers: [ActivatedRoute] from @Component() there is no need for that. RouterModule.forRoot() already provides everything that is required.
