在以前的版本中，loadChildren路径支持'app/path/to/module#Module'，但它不再起作用，而是使用相对路径'./路径/到/模块#模块'

In previous versions loadChildren path support with 'app/path/to/module#Module' but it's not working anymore, instead of that use relative path './path/to/module#Module'

Angular社区一直在回答我提出的问题，请在下面找到答复.

根据角度社区的回应，他们将更新文档.

用途需要从

const routes: Routes = [
  {
    path: 'customers',
    loadChildren: 'app/customers/customers.module#CustomersModule'
  },
  {
    path: 'orders',
    loadChildren: 'app/orders/orders.module#OrdersModule'
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
];

到

const routes: Routes = [
  {
    path: 'customers',
    loadChildren: './customers/customers.module#CustomersModule'
  },
  {
    path: 'orders',
    loadChildren: './orders/orders.module#OrdersModule'
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
];
