在子目录中部署时,Angular 6路径路径不适用于直接URL

import { NgModule } from '@angular/core';
import { Routes,RouterModule } from '@angular/router';
import { HomeComponent } from './public/home/home.component';

const routes: Routes = [
  {
    path: 'customers',loadChildren: '../app/customers/customers.module#CustomersModule'
  },{
    path: 'admin',loadChildren: '../app/admin/admin.module#AdminModule'
  },{
    path: 'home',component: HomeComponent
  },{
    path: '**',redirectTo: 'home',}
];

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

这些在开发环境下工作正常.
如果我直接打开localhost：4200 / home,它就会登陆到预期的页面.

但是,如果我直接打开www.domain.com/myngapp/home,那么使用Ng build –prod –base-href = / myngapp /的内置和部署只能在www.domain.com/myngapp上运行,然后它给出了404未找到的错误.
