[loadChildred的角度生产构建问题

Question

我已经在这个项目上工作了大约5个月，看起来还不错。但是在尝试使用CI / CD之后，我遇到了一个新问题。构建过程可以在笔记本电脑和台式机系统中正常运行，但是当我尝试像CI / CD运行器那样模拟过程时，我遇到了相同的错误：

ERROR in ./src/app/app-routing.module.ts 7:30
Module parse failed: Unexpected token (7:30)
You may need an appropriate loader to handle this file type.
| import { PinPrintComponent } from 'src/app/modules/user-actions/pin-print/pin-print.component';
| import { InvoicePrintComponent } from 'src/app/modules/user-actions/invoice-print/invoice-print.component';
> var ɵ0 = function () { return import("./modules/user-actions/user-actions.module.ngfactory").then(function (mod) { return mod.UserActionsModuleNgFactory; }); }, ɵ1 = function () { return import("./modules/user-panel/user-panel.module").then(function (mod) { return mod.UserPanelModule; }); };
| var routes = [
|     {

我通常要做的是使用以下命令进行构建： ng build --prod 但是为了模拟CI / CD运行程序的情况，我使用了： ./node_modules/@angular/cli/bin/ng build --progress false --prod

这是我的app-routing.module：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AuthGuard } from './services/auth.guard';
import { AuthenticatedAppResolver } from './services/resolver.service';

const routes: Routes = [
  {
    path: '',
    loadChildren: () => import('./modules/user-actions/user-actions.module').then(mod => mod.UserActionsModule)
  },
  {
    path: 'panel',
    loadChildren: () => import('./modules/user-panel/user-panel.module').then(mod => mod.UserPanelModule),
    canActivate: [AuthGuard],
    resolve: [AuthenticatedAppResolver]
  },
  {
    path: '**',
    redirectTo: '/panel/dashboard'
  }
];

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

还有我的package.json，如果它会响起铃声：

Answer 1

在Angular 8中，您可以将target更改为es6。 Angular CLI build 2版本的项目。 （对于现代浏览器和旧浏览器）。

要使用此滑块import('./modules/user-actions/user-actions.module').then(mod => mod.UserActionsModule)，我们也必须更新tsconfig。

tsconfig

"compilerOptions": {
    ...
    "module": "esnext",
    "target": "es6",
    "lib": [
      "es2018",
      "dom", // Maybe you don't need it
      "dom.iterable" // Maybe you don't need it
    ],
    ...
}
