Después de actualizar a angular 4, siempre obtengo el mismo error durante la compilación con angular-cli:

 ERROR in Cannot use 'in' operator to search for 'providers' in null

esta es mi app.modules.ts:

 const authenticatedRoutes: Route[] = [ { path: 'app', component: TsComponent, children: routingConfig }, { path: '**', redirectTo: 'app/cockpit', pathMatch: 'full' } ]; const routes: Route[] = [ { path: 'login', component: LoginComponent, canActivate: [StartupActivationGuard] } ]; @NgModule({ declarations: [ AppComponent, LoginComponent ], imports: [ BrowserModule, FormsModule, GlobalSharedModule.forRoot(), TsModule, AuthModule.forRoot(), StartupModule.forRoot(), MaterialModule, RouterModule.forRoot(routes) ], providers: [ { provide: ErrorHandler , useClass: TimeShepherdExceptionHandler } ], entryComponents: [AppComponent], bootstrap: [AppComponent] }) export class AppModule { } authenticatedRoutes.reduce((routeCollection, route: Route) => { route.canActivate = defaultGuards; routeCollection.push(route); return routeCollection; }, routes); const appRouterProviders = RouterModule.forRoot(routes);

Y aquí mi app.routes.ts:

 const defaultGuards: any[] = [ AuthActivationGuard ]; const authenticatedRoutes: Route[] = [ { path: '', redirectTo: 'app/cockpit', pathMatch: 'full' }, { path: 'app', component: TsComponent, children: routingConfig }, { path: '**', redirectTo: 'app/cockpit', pathMatch: 'full' } ]; const routes: Route[] = [ { path: 'login', component: LoginComponent, canActivate: [StartupActivationGuard] } ]; authenticatedRoutes.reduce((routeCollection, route: Route) => { route.canActivate = defaultGuards; routeCollection.push(route); return routeCollection; }, routes); export const appRouterProviders = RouterModule.forRoot(routes);

También trabajo con una subruta en otro directorio ts/ts.routes.ts:

 export const routingConfig = [ { path: 'start', component: StartComponent }, { path: 'logbook', component: LogBookComponent }, { path: 'example', component: ExampleComponent }, { path: 'dev', component: DevComponent }, { path: 'journal', component: JournalComponent}, { path: 'cockpit', component: CockpitComponent}, { path: 'reports', component: ReportsComponent} ]; export const routing = RouterModule.forChild(routingConfig);

¿Alguna idea de por qué me sale el error?
