Angular2 : EXCEPTION: No provider for Angulartics2GoogleAnalytics

Question

I am trying to use angulartics2 with my application.

I have configured correctly as it mentioned in the document.

Note: There is no place it is mentioned to add the provider as a dependency..

When i try to run the application, it shows the error as below.

EXCEPTION: No provider for Angulartics2GoogleAnalytics! Error: DI Error at NoProviderError.ZoneAwareError (zone.js:811) at NoProviderError.BaseError [as constructor] (core.umd.js:1186) at NoProviderError.AbstractProviderError [as constructor] (core.umd.js:1371) at new NoProviderError (core.umd.js:1411) at ReflectiveInjector_.throwOrNull (core.umd.js:3394) at ReflectiveInjector.getByKeyDefault (core.umd.js:3433) at ReflectiveInjector.getByKey (core.umd.js:3380) at ReflectiveInjector.get (core.umd.js:3140) at AppModuleInjector.NgModuleInjector.get (core.umd.js:8996) at CompiledTemplate.proxyViewClass.AppView.injectorGet (core.umd.js:12465) at CompiledTemplate.proxyViewClass.DebugAppView.injectorGet (core.umd.js:12845) at CompiledTemplate.proxyViewClass.View_AppComponent_Host0.createInternal (/AppModule/AppComponent/host.ngfactory.js:15) at CompiledTemplate.proxyViewClass.AppView.createHostView (core.umd.js:12421) at CompiledTemplate.proxyViewClass.DebugAppView.createHostView (core.umd.js:12829) at ComponentFactory.create (core.umd.js:7766) 1: https://github.com/angulartics/angulartics2

App.component.ts

import { Component } from '@angular/core';
import { Angulartics2GoogleAnalytics } from 'angulartics2';
@Component({
  selector: 'my-app',
  moduleId: module.id,
  templateUrl: `./app.component.html`,
  styleUrls: ['/app.componenet.css']
})
export class AppComponent {
title = 'Angular2 google analytics';
constructor(angulartics2GoogleAnalytics: Angulartics2GoogleAnalytics) {}
}

app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }  from './app.component';
import { HttpModule } from '@angular/http';
import { FormsModule }   from '@angular/forms';
import { Angulartics2Module, Angulartics2GoogleAnalytics } from 'angulartics2';
@NgModule({
  imports:      [ HttpModule, BrowserModule, FormsModule, Angulartics2Module.forRoot([ Angulartics2GoogleAnalytics ])],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ],

Yes, it should be done like you've done. This may happen if the modules became duplicated, and `Angulartics2GoogleAnalytics` refers to different classes in different modules. You have `App.component.ts` but import `./app.component`, this may indicate that you were careless with case, and it would lead to module duplication. I would suggest to check if `Angulartics2GoogleAnalytics` is really the same class in all modules, as it were suggested in the answer in dupe question. — Estus Flask, Jan 29 '17 at 08:27
To make sure, by 'it'` you mean that you tried to expose `Angulartics2GoogleAnalytics` as `window` property in both classes, and it was `===` equal when you compared it? If you can't provide [MCVE](http://stackoverflow.com/help/mcve) that can replicate the issue, I don't think that anything can be suggested as an answer here. — Estus Flask, Jan 29 '17 at 13:11

use providers to initiate your providers in component.

 @Component({
    selector: 'yourselector',
    styleUrls: [''],
    templateUrl: '',
    providers: [Angulartics2GoogleAnalytics]
})

Try this.

The providers block is a required piece! – Bwvolleyball Jun 24 '17 at 04:25

Your problem should reside in your constructor:

constructor(angulartics2GoogleAnalytics: Angulartics2GoogleAnalytics) {}

you should add e.g public in front of your provider:

constructor(public angulartics2GoogleAnalytics: Angulartics2GoogleAnalytics) {}

Strangely enough, making this public in the injector is also required. I had this as private, and flipping it to public fixed it. – Bwvolleyball Jun 24 '17 at 04:25
