“No provider for AuthGuard!” using CanActivate in Angular 2

Question

EDIT : Obviously this is outdated, now you provide your guard at the providers array in an NgModule. Watch other answers or official documentation

Answer 1

Actually, it was only a typo in an import...

I was typing

import { AuthGuard } from './../Authentification/auth.guard';

instead of

import { AuthGuard } from './../authentification/auth.guard';

making it not working but at the same time not displaying me any error...
