错误 NG8001：'nz-layout' 不是已知元素

Question

我从 NG-ZORRO 复制的所有东西，我也导入了 NgZorroAntdModule，但是当我尝试构建项目时遇到了这个错误。

pages/welcome/welcome 中的错误。component.ts:8:5 - 错误 NG8001：'nz-layout' 不是已知元素：

如果 'nz-layout' 是一个 Angular 组件，则验证它是该模块的一部分。
如果 'nz-layout' 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。

下面是我的代码：欢迎模块

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

import { WelcomeRoutingModule } from './welcome-routing.module';

import { WelcomeComponent } from './welcome.component';

Answer 1

最后，我解决了这个问题。这是因为 Route 配置，它应该与 loadChildren 一起使用，而不是使用 component

const routes: Routes = [
  { path: '', pathMatch: 'full', redirectTo: '/login' },
  { path: 'login', loadChildren: () => import('./login/login.module').then(m => m.LoginModule) },
  { path: 'pages', loadChildren: () => import('./pages/pages.module').then(m => m.PagesModule)}
];

以前是这样的，这是不正确的：

const routes: Routes = [
  { path: '', pathMatch: 'full', redirectTo: '/login' },
  { path: 'login', component: LoginComponent },
  { path: 'pages', component: PagesComponent }
];

Answer 2

在 app.module

的声明中注册组件

 @NgModule({
   declarations: [AppComponent, LoginComponent, PagesComponent],
   ...
 })
