'component'不是Angular 6中的已知元素

我在使用angular时遇到问题，这是我的项目结构（从app文件夹开始，请查看super-admin文件夹）：

- Modules
---- home [+]
---- admin [+]
---- super-admin
-------- super-admin-routing.module.ts
-------- super-admin.module.ts
-------- (And html, scss, component file)
-------- pages
------------ auth [+]
------------ unauth [+]
------------ shared
---------------- shared.component.ts
---------------- (And html, scss file)
- cores [+]
- config [+]
- shared [+]
- strores [+]
- app-routing.module.ts
- app.module.ts

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
@NgModule({
  declarations: [
    AppComponent,

  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

APP-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './modules/home/home.component';
import { AdminComponent } from './modules/admin/admin.component';
import { SuperAdminComponent } from './modules/super-admin/super-admin.component';

const routes: Routes = [
    {
        path: "",
        component: HomeComponent
    },
    {
        path: "home",
        component: HomeComponent
    },
    {
        path: "admin",
        component: AdminComponent
    },
    {
        path: "super-admin",
        component: SuperAdminComponent,
        loadChildren: './modules/super-admin/super-admin.module#SuperAdminModule'
    },
    {
        path: "**",
        component: HomeComponent
    }
];

@NgModule({
    declarations: [
        HomeComponent,
        AdminComponent,
        SuperAdminComponent
    ],
    imports: [RouterModule.forRoot(routes)],
    exports: [RouterModule]
})
export class AppRoutingModule { }

超admin.module.ts

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

import { SuperAdminRoutingModule } from './super-admin-routing.module';
import { SharedComponent } from './pages/shared/shared.component';

@NgModule({
  imports: [
    CommonModule,
    SuperAdminRoutingModule
  ],
  declarations: [SharedComponent]
})
export class SuperAdminModule { }

超级管理员，routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './pages/login/login.component';
import { AuthComponent } from './pages/auth/auth.component';


const routes: Routes = [
    {
        path: "login",
        component: LoginComponent
    },
    {
        path: "",
        component: AuthComponent,
        loadChildren: "./pages/auth/auth.module#AuthModule"
    },
    {
        path: "home",
        component: AuthComponent,
        loadChildren: "./pages/auth/auth.module#AuthModule"
    },
    {
        path: "**",
        component: AuthComponent
    },

];

@NgModule({
    declarations: [
        LoginComponent,
        AuthComponent
    ],
    imports: [RouterModule.forChild(routes)],
    exports: [RouterModule]
})
export class SuperAdminRoutingModule { }

超admin.component.html

<router-outlet></router-outlet>
<app-shared></app-shared>

最后是shared.component.ts文件

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

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

  constructor() { }

  ngOnInit() {
  }

}

请查看 super-admin.module.ts 文件，我在 super-admin.module.ts 中导入并声明了ShareComponent但我无法在 super-admin.component.html 中使用它，它说：

'app-shared'不是已知元素：如果'app-shared'是Angular组件，则验证它是否是此模块的一部分 . 如果'app-shared'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 .

我想我错过了什么？

我 ng s 它已经7次但它仍然不起作用

angular typescript

    由于你的super-admin.component属于app.module.ts，你需要从SuperAdminModule导出 SharedComponent 并在app.module.ts中导入 SuperAdminModule .

    将super-admin.module更改为，

    @NgModule({
  imports: [
    CommonModule,
    SuperAdminRoutingModule
  ],
  declarations: [SharedComponent],
  exports : [SharedComponent]
})

    EDIT 如评论中所述，将其添加到app.routing.module.ts中

    @NgModule({
    declarations: [
        HomeComponent,
        AdminComponent,
        SuperAdminComponent
    ],
    imports: [RouterModule.forRoot(routes), SuperAdminModule],
    exports: [RouterModule]
})
export class AppRoutingModule { }

    如果要声明模块中的任何组件并想要在其他模块中导入，请确保导出组件 .

    super-admin.module as，

    @NgModule({
      imports: [
        CommonModule,
        SuperAdminRoutingModule
      ],
      declarations: [SharedComponent],
      exports : [SharedComponent]
    })
export class SuperAdminModule { }

    将组件导入其他模块 . 您必须确保将共享模块导入到使用导出组件的模块中 .

    app-routing.module.ts

    @NgModule({
    declarations: [
        HomeComponent,
        AdminComponent,
        SuperAdminComponent
    ],
    imports: [RouterModule.forRoot(routes), SuperAdminModule],
    exports: [RouterModule]
})
export class AppRoutingModule { }
