Angular 6使用映射生成路由

Question

我想在网址上定义网站语言。例如"mysite.com/en/blabla“。但我为每个客户提供了不同的语言。如果客户不支持英语，angular应该返回404，我尝试这样做：

const languages:Routes = Object.getOwnPropertyNames(environment.trader.langList).map(path => {
  return {
    path, component: OutComponent,
    children: [
      { path: 'place-bet', loadChildren: '../../desktop/placebet/placebet.module#PlacebetModule' },
      { path: 'games', loadChildren: '../../desktop/games/games.module#GamesModule' },
      { path: 'dashboard', loadChildren: '../../desktop/dashboard/dashboard.module#DashboardModule' }]
  };
})
debugger;

const OutRoutes: Routes = [
  ...languages
];

export const OutRouter = RouterModule.forChild(OutRoutes);

我从环境中获取语言，并为每种语言生成路由。这适用于运行时，但当我编译时，它给出一个错误："ERROR in Cannot read property 'loadChildren‘of undefined“。它不能在编译时编译映射的路由。我怎么解决它呢？
