Uncaught Error: Template parse errors:'router-outlet' is not a known element:

Hi Guys ,

Today I have faced this error :

Uncaught Error: Template parse errors:'router-outlet' is not a known element:

The solution is to add the following line in app.module.ts highlighted in Yellow.

@NgModule({
imports: [
    BrowserModule,
    RouterModule.forRoot(appRoutes),
    FormsModule             
],

The complete console log is as below:

Uncaught Error: Template parse errors:

'router-outlet' is not a known element:

1. If 'router-outlet' is an Angular component, then verify that it is part of this module.

2. If 'router-outlet' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("

   <a routerLink= "/explore"> Explore </a>

 </nav>

 [ERROR ->]<router-outlet></router-outlet>

<form #form="ngForm" (ngSubmit)="onSubmit(form.value)">

 <label>Name:"): ng:///AppModule/AppComponent.html@5:1
