Angular Router-outlet 未在生产模式下填充 [英] Angular Router-outlet not populated in production mode

问题描述

我正在尝试在生产模式下构建我的 Angular 应用程序，但遇到了一个奇怪的错误.

I'm trying to build my Angular app in production mode and encounter a weird error.

在开发模式下一切正常.不过，在生产模式下，当我打开index.html"时，我被正确重定向到我想要的默认路径，但我的 router-outlet 没有填充.

In development mode everything works fine. In production mode though, when I open "index.html", I am properly redirected to my desired default path but my router-outlet is not populated.

我的 app-routing.module.ts:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { GraphMapComponent } from './graph-map/graph-map.component';
import { ZoneEditorComponent } from './zone-editor/zone-editor/zone-editor.component';
import { ZonesOverviewComponent } from './zone-editor/components/zones-overview/zones-overview.component';
import { ZoneConfigurationComponent } from './zone-editor/components/zone-configuration/zone-configuration.component';
import { NewZoneSelectionComponent } from './zone-editor/components/new-zone-selection/new-zone-selection.component';

const routes: Routes = [
  { path: '', redirectTo: '/zone-editor/zones', pathMatch: 'full' },
  {
    path: 'path-editor',
    component: GraphMapComponent
  },
  {
    path: 'zone-editor',
    component: ZoneEditorComponent,
    children: [
      {
        path: 'zones',
        component: ZonesOverviewComponent,
        data: { animation: 'isLeft' }
      },
      {
        path: 'add-zone',
        component: NewZoneSelectionComponent,
        data: { animation: 'isRight' }
      },
      {
        path: 'zone/:id',
        component: ZoneConfigurationComponent,
        data: { animation: 'isRight' }
      },
      {
        path: '',
        redirectTo: 'zones',
        pathMatch: 'full'
      }
    ]
  }
];
@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

在这里您可以看到路由器插座没有被填充:

Here you can see how the router-outlet does not get populated:

我尝试了不同的方法，但我无法弄清楚.它在开发模式下工作.当我在 ng serve 期间调用 enableProdMode(); 时，它也有效.

I have tried different things but I cannot figure it out. It works in dev-mode. It also works when I call enableProdMode(); during ng serve.

它仅在我使用 build --prod 并执行缩小/优化等操作时不起作用.

It only does not work when I use build --prod and do the minification/optimization/etc.

任何帮助表示赞赏.我可以在必要时提供更多信息，但我不确定是哪个.

Any help appreciated. I can provide more information when necessary, I'm just not sure which.

推荐答案

我遇到了同样的问题，不得不禁用 aot 并进行构建优化.我不知道为什么必须这样做，我认为它非常愚蠢，但它是我唯一的解决方案.

I hade the same issue and had to disable aot and build optimization. I dont know why this has to be done and I think its super stupid but it was the only solution for me.

您可以通过 angular.json 执行此操作.只需评论两个相应的条目:

You can do this via angular.json. Just comment the two corresponding entries:

  [...]
  "configurations": {
        "production": {
          "fileReplacements": [
            {
              "replace": "src/environments/environment.ts",
              "with": "src/environments/environment.prod.ts"
            }
          ],
          "optimization": true,
          "outputHashing": "all",
          "sourceMap": false,
          "extractCss": true,
          "namedChunks": false,
          //"aot": true,
          "extractLicenses": true,
          "vendorChunk": false,
          //"buildOptimizer": true
        }
      }
    },
    [...]

或直接在命令行中:

ng build --prod --build-optimizer=false --aot=false
