如何在 Nebular 中正确实现侧边栏？

Question

It displays a blank page when I add sidebar. It does not give me any error messages. If I remove it, it returns to normal.

    <nb-layout-column>Content</nb-layout-column>
</nb-layout>

home.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { HomeComponent } from './home.component';
import { NbActionsModule, NbButtonModule, NbContextMenuModule, NbFormFieldModule, NbIconModule, NbInputModule, NbLayoutModule, NbMenuModule, NbSearchModule, NbSidebarModule, NbTabsetModule, NbUserModule } from '@nebular/theme';
import { RouterModule } from '@angular/router';



@NgModule({
  declarations: [
    HomeComponent
  ],
  imports: [
    CommonModule,
    RouterModule,
    NbLayoutModule,
    NbActionsModule,
    NbIconModule,
    NbContextMenuModule,
    NbTabsetModule,
    NbButtonModule,
    NbSearchModule,
    NbUserModule,
    NbFormFieldModule,
    NbInputModule,
    NbSidebarModule,
    NbMenuModule,
  ]
})
export class HomeModule { }

I just want to add a sidebar to my project. I follow the code in the documentation but still, it doesn't work.

Add NbSidebarService to the list of providers

@NgModule({
  ...
  providers: [NbSidebarService],
  ...
})
export class AppModule {}
