【问题描述】：

在模块中声明组件名称后，出现以下错误

这是我的学习详细信息模块，其中包含我在此处映射的所有相关组件

    import  NgModule  from '@angular/core';
    import  CommonModule  from '@angular/common';
    import  StudyDetailsComponent  from './study-details.component';
    import  RouterModule  from '@angular/router';

    import  PartialsModule  from '../../partials/partials.module';
    import  CoreModule  from '../../../core/core.module';

    /* material components */
    import  MaterialModule  from '../../../shared/modules/material.module';
    /* import componenets for study details */
    import  BasicInformationComponent  from './basic-information/basic-information.component';
    import  MaintenanceComponent  from './maintenance/maintenance.component';
    import  ProcedureCostComponent  from './maintenance/procedure-cost/procedure-cost.component';
    import  CountryListComponent  from './maintenance/procedure-cost/country-list/country-list.component';
    import  StudyListComponent  from './maintenance/procedure-cost/country-list/study-list/study-list.component';
    import  MatchSiteComponent  from './match-site/match-site.component';
    import  FormsModule  from '@angular/forms';
    import  NgxFlagPickerModule  from 'ngx-flag-picker';
    import  DialogCTMSComponent  from './match-site/dialog-ctms/dialog-ctms.component';
    import  MatDialogModule  from '@angular/material';
    //import  DialogCTMSComponent  from '../study-details/match-site/dialog-ctms/dialog-ctms.component';



    @NgModule(
      declarations: [StudyDetailsComponent, BasicInformationComponent, MaintenanceComponent, ProcedureCostComponent, CountryListComponent, StudyListComponent, MatchSiteComponent ],
      imports: [PartialsModule, MaterialModule,MatDialogModule,
        CoreModule,FormsModule,NgxFlagPickerModule,

        CommonModule, RouterModule.forChild([
          
            path: '',
            component: StudyDetailsComponent
          ,
        ])
      ],

      entryComponents: [
        DialogCTMSComponent
      ],

这是我遇到的错误

Error: Uncaught (in promise): Error: Component DialogCTMSComponent is not part of any NgModule or the 
module has not been imported into your module. Error: Component DialogCTMSComponent is not part of 
any NgModule or the module has not been imported into your module.

请让我知道我在这里做错了什么

【参考方案1】：

你也需要在声明下添加它

 declarations: [StudyDetailsComponent, BasicInformationComponent, MaintenanceComponent, ProcedureCostComponent, CountryListComponent, StudyListComponent, MatchSiteComponent, DialogCTMSComponent ],

【讨论】：

嗨@Sajeetharan 感谢您的及时回答我已经创建了其他组件，当时没有发生此错误，为什么现在请告诉我

所有组件都应在模块内声明。如果您使用cli创建，它将自动添加到声明中

这是正确的，我用 CLi 创建只需要添加入口组件，因为如果我被删除 entryComponent 我得到错误这不是在入口组件中添加请告诉我原因

你需要了解***.com/questions/39756192/…

如果可能的话，您能否为我的问题提供支持投票，谢谢
