Can't bind to 'routerLink' since it isn't a known property

You need to add RouterModule to imports of every @NgModule() where components use any component or directive from (in this case routerLink and <router-outlet>.

import {RouterModule} from '@angular/router';@NgModule({   declarations:[YourComponents],   imports:[RouterModule]

declarations: [] is to make components, directives, pipes, known inside the current module.

exports: [] is to make components, directives, pipes, available to importing modules. What is added to declarations only is private to the module. exports makes them public.

You are missing either the inclusion of the route package, or including the router module in your main app module.

Make sure your package.json has this:

"@angular/router": "^3.3.1"

Then in your app.module import the router and configure the routes:

import { RouterModule } from '@angular/router';imports: [        RouterModule.forRoot([            {path: '', component: DashboardComponent},            {path: 'dashboard', component: DashboardComponent}        ])    ],

Update:

Move the AppRoutingModule to be first in the imports:

imports: [    AppRoutingModule.    BrowserModule,    FormsModule,    HttpModule,    AlertModule.forRoot(), // What is this?    LayoutModule,    UsersModule  ],

I'll add another case where I was getting the same error but just being a dummy. I had added [routerLinkActiveOptions]="{exact: true}" without yet adding routerLinkActive="active".

My incorrect code was

<a class="nav-link active" routerLink="/dashboard" [routerLinkActiveOptions]="{exact: true}">  Home</a>

when it should have been

<a class="nav-link active" routerLink="/dashboard" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">  Home</a>

Without having routerLinkActive, you can't have routerLinkActiveOptions.
