访问路由时出现SSRAngularUniversal服务器错误

确保在server.ts文件中设置了正确的路由。例如：

const routes: Routes = [
  { path: '', redirectTo: 'home', pathMatch: 'full' },
  { path: 'home', component: HomeComponent },
  { path: 'about', component: AboutComponent },
  { path: 'contact', component: ContactComponent },
  { path: '**', component: PageNotFoundComponent }
];

确保在app.module.ts中注册了所有的组件。例如：

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    AboutComponent,
    ContactComponent,
    PageNotFoundComponent
  ]
})

确保在app.module.ts中导入了所有需要的模块。例如：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { ContactComponent } from './contact/contact.component';
import { PageNotFoundComponent } from './page-not-found/page-not-found.component';
@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    AboutComponent,
    ContactComponent,
    PageNotFoundComponent
  ],
  imports: [
    BrowserModule.withServerTransition({appId: 'my-app'}),
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

确保不存在不兼容的依赖项。例如：

"dependencies": {
  "@angular/compiler": "^7.2.0",
  "@angular/platform-server": "^7.2.0",
  "rxjs": "^6.3.3",
  "zone.js": "^0.8.26"
}

如果在组件中使用了注入器，请确保在构造函数中正确注入。例如：

import { Component, Inject, PLATFORM_ID } from '@angular/core';
import { isPlatformBrowser } from
