This happens when you try to add a "routerLink" attribute to a component in Angular. 

Solution

import the {RouterModule} to your module like this:

import {RouterModule} from '@angular/router';

@NgModule({
  imports: [
      RouterModule,
      RouterModule.forChild([
          {
              path: '',
              component: HomePage,
              data: {shouldDetach: true}
          },
      ]),
  ],
  declarations: [
    HomePage
  ]
})
export class HomeModule {
}
