只要在应用程序中出现路由路径和组件声明，就会出现 Angular7 空白页面-routes.module.ts

Question

我正在设置一个新的 angular 应用程序，每当我在 app-routing.module.ts 文件中指定我的路由时，页面就会呈现空白。

const routes: Routes = [
  {path: '/dashboard', component: DashboardComponent},
  {path: '/login', component: LoginComponent},
];

但是，如果我将其注释掉，它就会正确呈现。

const routes: Routes = [
  // {path: '/dashboard', component: DashboardComponent},
  // {path: '/login', component: LoginComponent},
];

我的 app-routing.moduel.ts 文件

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './login/login.component';
import { DashboardComponent } from './dashboard/dashboard.component';
import { UserProfileComponent } from './user-profile/user-profile.component';
import { RegisterComponent } from './register/register.component';


const routes: Routes = [
  {path: '/dashboard', component: DashboardComponent},
  {path: '/login', component: LoginComponent},
];

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

export const appRouteComponents = [
  LoginComponent,
  DashboardComponent,
  UserProfileComponent,
  RegisterComponent
];

我已经在 app.module.ts 文件中导入了 appRouteComponents

这是app.module.ts文件

import { MaterialDesignModule } from './material';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';

import { AppRoutingModule, appRouteComponents } from './app-routing.module';
import { AppComponent } from './app.component';


@NgModule({
  declarations: [
    AppComponent,
    appRouteComponents,
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    MaterialDesignModule,
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

尝试删除路由中的 /，如下所示。

const routes: Routes = [
  { path: 'dashboard', component: DashboardComponent },
  { path: 'login', component: LoginComponent },
];

只要在应用程序中出现路由路径和组件声明，就会出现 Angular7 空白页面-routes.module.ts

Angular7 Blank page appears whenever route path and component declaration occurs in the app-routes.module.ts
