[typescript] Error: Uncaught (in promise): Error: Cannot match any routes Angular 2

I also had the same issue. Tried all ways and it didn't work out until I added the following in app.module.ts

import { Ng4LoadingSpinnerModule } from 'ng4-loading-spinner';

And add the following in your imports in app.module.ts

Ng4LoadingSpinnerModule.forRoot()

This case might be rare but I hope this helps someone out there
