Error: exports is not defined - Nativescript

im tring to test the app with jasmine, and when the compilation is done i get this message:

Chrome 67.0.3396 (Windows 10 0.0.0) ERROR
  {
    "message": "Uncaught ReferenceError: exports is not defined\nat app/app-routing.module.js:2:23\n\nReferenceError: exports is not defined\n    at app/app-routing.module.js:2:23",
    "str": "Uncaught ReferenceError: exports is not defined\nat app/app-routing.module.js:2:23\n\nReferenceError: exports is not defined\n    at app/app-routing.module.js:2:23"
  }

i tried to add export = 0 on the top of the file but i get another error: An export assignment cannot be used in a module with other exported elements.

and in the browser (karma):

app-routing.module.ts:

import { NgModule } from "@angular/core";
import { Routes } from "@angular/router";
import { NativeScriptRouterModule } from "nativescript-angular/router";
import { LoggedInLazyLoadGuard } from "./logged-in-lazy-load.guard";

const routes: Routes = [
    { path: "", redirectTo: "/home", pathMatch: "full" },
    { path: "login", loadChildren: "./login/login.module#LoginModule" },
    { path: "home", loadChildren: "./home/home.module#HomeModule", canLoad: [LoggedInLazyLoadGuard] }
];

@NgModule({
    imports: [NativeScriptRouterModule.forRoot(routes)],
    exports: [NativeScriptRouterModule]
})
export class AppRoutingModule { }
