错误：在MAC设备上加载块5失败

Question

我们在angular 6和asp.net MVC 5中有一个基于云的应用程序
我们的应用程序可以在Android，Chrome上正常运行。在MAC上不起作用。因此，我们在苹果ipad上安装了chrome并尝试运行我们的应用程序。登录成功，并且显示仪表板，但是当我尝试打开另一个页面（例如，约会）时，它显示错误为“错误：加载块5失败”

请帮助。任何帮助，将不胜感激。谢谢

app-routing.module.ts的代码：

import { NgModule } from '@angular/core';  
import { Routes, RouterModule } from '@angular/router';  
const routes: Routes = [  
{ path: '', loadChildren: () => import('./login/login.module').then(m => m.LoginModule) },  
];  
@NgModule({  
imports: [RouterModule.forRoot(routes)],  
exports: [RouterModule]  
})  
export class AppRoutingModule { }

layout-routing.module.ts的代码：

import { NgModule } from '@angular/core';  
import { Routes, RouterModule } from '@angular/router';  
import { LayoutComponent } from './layout.component';  

const routes: Routes = [  
{  
path: '',  
component: LayoutComponent,  
children: [  
{ path: 'dashboard', loadChildren: () => import('./dashboard/dashboard.module').then(m => m.DashboardModule) },  
{ path: 'appointment', loadChildren: () =>  
import('./TransactionComponent/appointment/appointment.module').then(m => m.AppointmentModule)}  
];  

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

约会代码。module.ts

import { NgModule } from '@angular/core';  
import { CommonModule } from '@angular/common';  
import { AppointmentComponent } from './appointment.component';  
import { AppointmentRoutingModule } from './appointment-routing.module';  
@NgModule({  
declarations: [AppointmentComponent],  
imports: [  
CommonModule,  
AppointmentRoutingModule,  
PageHeaderModule,  
NgbModule  
],  
providers: [AppointmentService]  
})  
export class AppointmentModule { }

对于Apple设备，路由无法正常工作。请帮忙。

谢谢。
