如果 'nb-card' 是一个 Angular 组件,则验证它是该模块的一部分

If 'nb-card' is an Angular component, then verify that it is part of this module

我在设置 nebular 侧边栏时遇到问题,因为我收到错误:

If 'nb-card' is an Angular component, then verify that it is part of this module.

src/app/pages/components/dashboard/dashboard 中的错误。component.html:5:2 - 错误 NG8001:'nb-card' 不是已知元素:

  1. 如果 'nb-card' 是一个 Angular 组件,则验证它是该模块的一部分。
  2. 如果 'nb-card' 是 Web 组件,则将 'CUSTOM_ELEMENTS_SCHEMA' 添加到此组件的“@NgModule.schemas”以禁止显示此消息。

功能模块:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { DashboardRoutingModule } from './dashboard-routing.module';
import { NbSidebarModule, NbLayoutModule } from '@nebular/theme';

import {
  NbButtonModule,
  NbCardModule,
  NbProgressBarModule,
  NbTabsetModule,
  NbUserModule,
  NbIconModule,
  NbSelectModule,
  NbListModule,
  NbMenuModule,
} from '@nebular/theme';
@NgModule({
  declarations: [],
  imports: [
    CommonModule,
    DashboardRoutingModule,
    NbLayoutModule,
    NbSidebarModule,
    NbButtonModule,
    NbCardModule,
    NbProgressBarModule,
    NbTabsetModule,
    NbUserModule,
    NbIconModule,
    NbSelectModule,
    NbListModule,
    NbMenuModule,
  ]
})
export class DashboardModule { }

应用模块:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { NbThemeModule, NbLayoutModule } from '@nebular/theme';
import { NbEvaIconsModule } from '@nebular/eva-icons';
import { NbSidebarModule, NbMenuModule} from '@nebular/theme';

import { DashboardComponent } from './pages/components/dashboard/dashboard.component';



@NgModule({
  declarations: [
    AppComponent,
    DashboardComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    NbThemeModule.forRoot({ name: 'default' }),
    NbLayoutModule,
    NbEvaIconsModule,
    NbSidebarModule.forRoot(),
    NbMenuModule.forRoot(),
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

仪表板组件:

import { Component, OnInit } from '@angular/core';

import { NbMenuItem } from '@nebular/theme';

@Component({
  selector: 'app-dashboard',
  templateUrl: './dashboard.component.html',
  styleUrls: ['./dashboard.component.scss']
})
export class DashboardComponent implements OnInit {

  constructor() { }


  items: NbMenuItem[] = [
    {
      title: 'Profile',
      expanded: true,
      children: [
        {
          title: 'Change Password',
        },
        {
          title: 'Privacy Policy',
        },
        {
          title: 'Logout',
        },
      ],
    },
    {
      title: 'Shopping Bag',
      children: [
        {
          title: 'First Product',
        },
        {
          title: 'Second Product',
        },
        {
          title: 'Third Product',
        },
      ],
    },
    {
      title: 'Orders',
      children: [
        {
          title: 'First Order',
        },
        {
          title: 'Second Order',
        },
        {
          title: 'Third Order',
        },
      ],
    },
  ];

  ngOnInit(): void {
  }

}

仪表板组件 html:

<nb-layout>
  <nb-layout-header fixed>Company Name </nb-layout-header>

  <nb-sidebar>
    <nb-card>
      <nb-menu [items]="items" autoCollapse="true">
      </nb-menu>
    </nb-card>
  </nb-sidebar>

  <nb-layout-column>
    Page Content <button nbButton>Hello World</button>
  </nb-layout-column>
</nb-layout>

我们将不胜感激。

谢谢

看起来 dashboard.module 应该声明 dashboard.component 因为 NbCardModule 是在那里导入的。 atm 它在 app.module.

中声明

或者将 dashboard.module 导入到 app.module
