Question

我正在处理一些有角度的4应用程序，我想在@ng-bootstrap/ng-bootstrap中导入一些模块。问题是，即使我有一个成功导入模块的自定义模块，我的另一个模块无法导入它并发出如下警告： WARNING in ./src/app/main/layout/fail/fail/fail.component.ts 151:83-96 "export 'NgbTimeStruct' was not found in '@ng-bootstrap/ng-bootstrap' 我非常肯定它已正确安装，因为我说我有另一个模块可以导入它没有问题，但我错过了什么？我已经包含了module.ts和component.ts文件中所需的模块和组件！

这些是我需要解决的问题：来自CalendarEvent的{{1}}; 来自angular-calendar

的NgbDateStruct和NgbTimeStruct

以下是我的代码：

模块成功导入模块：

success.module.ts：

@ngx-translate/core

success.component.ts：

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { SuccessComponent } from './success.component';
import { SuccessRoutingModule } from './successrouting.module';
import { FormsModule } from '@angular/forms';
import { CalendarModule } from 'angular-calendar';
import { UtilsModule } from '../util/module';
import { FailModule } from '../../fail/fail/fail.module';
//import { FailComponent } from '../../event/eventmodify/eventmodify.component'; // I am trying to use the failed module in this module
import { NgbModalModule, NgbDatepickerModule, NgbTimepickerModule } from '@ng-bootstrap/ng-bootstrap';
import { ElementsModule } from '../../../../shared/components/elements/elements.module';
import { TranslateModule } from '@ngx-translate/core';

@NgModule({
  imports: [
    CommonModule,
    SuccessDemoRoutingModule,
    FormsModule,
    NgbModalModule.forRoot(),
    NgbDatepickerModule.forRoot(),
    NgbTimepickerModule.forRoot(),
    CalendarModule.forRoot(),
    UtilsModule,
    FailModule,
    ElementsModule,
    TranslateModule
  ],
  declarations: [SuccessDemoComponent],
  exports: [SuccessDemoComponent]
})
export class SuccessModule { }

模块无法导入模块：

fail.module.ts：

import { Component, AfterViewInit, ChangeDetectionStrategy, ViewChild, 
TemplateRef, ElementRef } from '@angular/core';
import { Router } from '@angular/router';
import { Location } from '@angular/common';
import { TranslateService } from '@ngx-translate/core';
import { jqxDataTableComponent } from 'jqwidgets-framework/jqwidgets-ts/angular_jqxdatatable';
import { EventModifyComponent } from '../../event/eventmodify/eventmodify.component';
import { EventValue } from '../../../service/event/structure/event.value';
import { EventService } from '../../../service/event/event.service.promise';
import { ValidateUtil } from '../../../../shared/validate/validate.util';
import { GeneralService } from 
'../../../service/general/general.service.promise';
import { GeneralValue } from '../../../service/general/structure/general.value';
import { ResponseValue } from '../../../service/event/structure/response.value';
import * as myGlobal from '../../../../shared/global/global';
import { WindowComponent } from '../../../../shared/components/elements/window/window.component';

import { startOfDay, endOfDay, subDays, addDays, endOfMonth, isSameDay, isSameMonth, addHours, getMinutes, getHours, getDate, getMonth, getYear, setSeconds, setMinutes, setHours, setDate, setMonth, setYear } from 'date-fns';
import { Subject } from 'rxjs/Subject';
import { NgbModal, NgbDateStruct, NgbTimeStruct } from '@ng-bootstrap/ng-bootstrap';
import { CalendarEvent, CalendarEventAction, CalendarEventTimesChangedEvent} from 'angular-calendar';

import 'angular-calendar/dist/css/angular-calendar.css';

... //out of the failed ones I need only NgbModal is included in the constructor

fail.component.ts：

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FailComponent } from './fail.component';
import { FormsModule } from '@angular/forms';
import { CalendarModule } from 'angular-calendar';
import { SuccessModule } from '../../success/success/success.module';
import { UtilsModule } from '../../success/util/module';
import { NgbModalModule, NgbDatepickerModule, NgbTimepickerModule } from '@ng-bootstrap/ng-bootstrap';
import { ElementsModule } from '../../../../shared/components/elements/elements.module';
import { TranslateModule } from '@ngx-translate/core';

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    CalendarModule.forRoot(),
    NgbModalModule.forRoot(),
    NgbDatepickerModule.forRoot(),
    NgbTimepickerModule.forRoot(),
    UtilsModule,
    ElementsModule,
    TranslateModule
  ],
  declarations: [FailComponent],
  exports: [FailComponent]
})
export class FailModule { }

关于如何让事情发挥作用的任何想法？谢谢你的建议。

事实证明，我双重导入模块，而Angular不喜欢它。我从失败模块中删除了成功模块的导入，然后它运行良好。我想如果真的需要两个自定义模块依赖彼此的人，最好不要通过导入两个模块来导入一些模块，如NgbModalModule两次。

而且我听说有人共享模块的最佳方法是将这些模块导入共享模块。

Angular 4 - 编译器在组件中找不到节点模块模块，但是有另一个模块可以成功导入它
