ng2-toastr not working in angular 2

I am trying to use ng2-toastr in my angular 2 app. I have followed all the instructions but the toastr fails to show up without any console error. I have also read somewhere that ng-toastr no longer works with angular 2 but have not found any valid documentation on that. I have searched for similar questions but have not found any suitable answer to my problem. any help would be appreciated.

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';
import{ ToastModule} from 'ng2-toastr/ng2-toastr';
import { BrowserAnimationsModule} from '@angular/platform-
browser/animations';
import "hammerjs"

import { CoreModule } from './core/core.module';

import { MODULE_ROUTES, MODULE_COMPONENTS } from './app.router'

@NgModule({
  declarations: [
    MODULE_COMPONENTS
],
imports: [
   BrowserModule,
   FormsModule,
   HttpModule,
   RouterModule.forRoot(MODULE_ROUTES),
   BrowserAnimationsModule,
   CoreModule,
   ToastModule.forRoot()
],
providers: [ ],
bootstrap: [MODULE_COMPONENTS]
})
export class AppModule { }

app.component.ts

import { Component, ViewContainerRef } from '@angular/core';
import { ViewEncapsulation } from '@angular/core';
import { ToastsManager } from 'ng2-toastr/ng2-toastr';

@Component({
  selector: 'wow-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
  constructor( public toastr: ToastsManager, private vRef: ViewContainerRef) 
  {
    this.toastr.setRootViewContainerRef(vRef);
    console.log(this.toastr);
  }

}

This is how I am calling toastr method in one of my components:

 login() {
   this.user_service.login(this.user).then((response) => {
     console.log(response)
     this.toastrManager.success('Successfully Logged in.')
   }

package.json

"dependencies": {
"@angular/animations": "^4.1.3",
"@angular/common": "^4.0.0",
"@angular/compiler": "^4.0.0",
"@angular/core": "^4.0.0",
"@angular/forms": "^4.0.0",
"@angular/http": "^4.0.0",
"@angular/platform-browser": "^4.0.0",

"jquery": "^3.2.1",

"zone.js": "^0.8.4"
},
"devDependencies": {
  "@angular/cli": "1.0.3",
  "@angular/compiler-cli": "^4.0.0",
  "@types/jasmine": "2.5.38" 
}

I have also added "../node_modules/ng2-toastr/bundles/ng2-toastr.min.css" in my angular-cli.json. this is console.log

[UPDATE]

I finally managed to solve the problem, thought to share it with all those who are stuck in the same issue. Please change the following code

import { ToastsManager } from 'ng2-toastr/ng2-toastr';

to

import { ToastsManager } from 'ng2-toastr';

since, the ToastsManager is exported from the parent directory and not from the subdirectory (atleast, in the versions of dependencies I am using).
