我刚刚升级到 Angular 9 并使用延迟加载创建了一些子路由。在这些更改之前，我的项目和我的路由运行良好，但在这两个更改之后，只有我的 HomeComponent 路由(路径:“”)正常工作，但是如果我尝试单击其他路由的链接(使用routerLink)，它根本不会重定向，如果我在浏览器中手动编写路由，它会给我一个没有错误的空白页面。
总结:项目和路由运行良好，但在我创建 Angular 延迟加载路由后，唯一可用的路由是默认路由 (HomeComponent)，如果我尝试单击指向其他路线的链接没有任何反应，如果我在浏览器中手动输入这些路线，它会给我一个没有错误的空白页面。
app.module.ts
@NgModule({

AppComponent,
HomeComponent,

Mugan86GoogleAnalyticsModule.forRoot({analyticsId: 'XXX', showLog: false}),

{provide: ErrorHandler, useClass: RollbarErrorHandler},
{provide: RollbarService, useFactory: rollbarFactory}
],

exports: [
SharedModule,
HomeModule,

})
export class AppModule {
}

})
export class HomeModule { }
app-routing.module.ts
export const routes: Routes = [
{path: '', pathMatch: 'full', component: HomeComponent}, // no route specified
{path: '', component: HomeComponent},
{path: 'sobre-nosotros', loadChildren: () => import('./components/about-us/about-us.module').then(m => m.AboutUsModule)},
{
path: 'preguntas-frecuentes',
loadChildren: () => import('./components/common-questions/common-questions.module').then(m => m.CommonQuestionsModule)
},
{path: 'sitemap', loadChildren: () => import('./components/sitemap/sitemap.module').then(m => m.SitemapModule)},
{path: '**', component: HomeComponent}, // fallback route (not found - 404)
];
@NgModule({
imports: [RouterModule.forRoot(routes, {initialNavigation: 'enabled', preloadingStrategy: PreloadAllModules})],
exports: [RouterModule]
})
export class AppRoutingModule {
}
作为示例，我将展示其中一条不起作用的路由的模块和路由模块:
about-us-module.ts
@NgModule({
declarations: [AboutUsComponent],
imports: [
AppModule,
CommonModule,
AboutUsRoutingModule,
]
})
export class AboutUsModule { }
about-us-routing.module.ts
const routes: Routes = [{path: '', component: AboutUsComponent}];
@NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule]
})
export class AboutUsRoutingModule {
}

我有另一个使用 Ivy 和子路由的项目，我只是按照与上述项目相同的步骤操作，但我发现了所描述的问题。
编辑
我刚刚删除了每条路由的延迟加载和模块/路由模块，应用程序再次运行。所以肯定问题是由延迟加载特性引起的。
最佳答案
请移除前两个 Home-Routes (HomeComponent)。
在 app-routing.module 中，您可以启用路由调试:
@NgModule({
imports: [
RouterModule.forRoot(routes, {enableTracing: true}),
也许您可以删除 {initialNavigation: 'enabled', preloadingStrategy: PreloadAllModules}。
您的代码看起来不错。希望调试能给大家更多信息。
AppRoutingModule 应该只在 AppModule 中使用。不允许在延迟加载的子模块之一中引用 AppRoutingModule。
在 AppModule 中导入 BrowserModule、BrowserAnimationsModule 和 AppRoutingModule。
尽量避免大的共享模块。请参阅:Lazy Loading Angular - Code Splitting NgModules with Webpack
