当我添加侧边栏时，它显示一个空白页面。它不给我任何错误信息。如果我删除它，它会恢复正常。

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 { }

我只是想在我的项目中添加一个侧边栏。我按照文档中的代码操作，但仍然不起作用。
