Question

我已经使用Angular 6创建了一个库并成功构建了它。将模块（ AdjudicationHistoriqueModule ）添加到库模块后，在构建库时会出现以下错误：

TypeError: Cannot read property 'isSkipSelf' of null
    at ProviderElementContext._getDependency (C:\Users\taha.manar\Documents\workspace\ADJUDICATION-IHM\node_modules\@angular\compiler\bundles\compiler.umd.js:11483:22)
    at C:\Users\taha.manar\Documents\workspace\ADJUDICATION-IHM\node_modules\@angular\compiler\bundles\compiler.umd.js:11428:64
    at Array.map (<anonymous>)
    at C:\Users\taha.manar\Documents\workspace\ADJUDICATION-IHM\node_modules\@angular\compiler\bundles\compiler.umd.js:11428:30
...

将下面的行添加到pulic_api.ts文件中时，我也遇到相同的错误

export * from './lib/historique/adjudication-historique.module';

adjudication-historique.module.ts

import { AlmCommonModule } from './../Common/alm-common.module';
import { AlmRootPageModule } from './../Common/root-page/root-page.module';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { AdjudicationHistoriqueRoutingModule } from './adjudication-historique-routing.module';
import { HistoriqueComponent } from './historique.component';
import { AdjudicationStructHistoriqueComponent } from './adjudication-struct-historique.component';
import { HistoriqueService } from './historique.service';

@NgModule({
  imports: [
CommonModule,AdjudicationHistoriqueRoutingModule,AlmRootPageModule,AlmCommonModule
  ],
  declarations: [HistoriqueComponent,AdjudicationStructHistoriqueComponent]
,
providers : [HistoriqueService]

})
export class AdjudicationHistoriqueModule { }

adjudication.module.ts（库模块）

import { HistoriqueService } from './historique/historique.service';
import { NgModule } from '@angular/core';
import { AdjudicationComponent } from './adjudication.component';

@NgModule({
  imports: [
  ],
  declarations: [AdjudicationComponent],
  exports: [AdjudicationComponent],
  providers: [HistoriqueService]
})
export class AdjudicationModule { }

P.S：我正在将项目从Angular 4升级到Angular 6

TypeError：无法读取null Angular 6的属性'isSkipSelf'
