无法绑定到“ pdfTitle”，因为它不是“ app-pdf-viewer”的已知属性

我尝试让延迟加载工作。但是当我删除de模块时，谁负责app.module中的延迟加载。该应用程序不再起作用。

谷歌搜索很多。更改代码

所以我有一个dossier.module.ts，像这样：

 imports: [
        RouterModule,
        CommonModule,
        ReactiveFormsModule,
        DossierRoutingModule,
        PdfViewerModule,
        SharedModule
        ],

  declarations: [
        DossierComponent,
        DossierCorrespondenceComponent,
        DossierCorrespondenceItemComponent,
        DossierEntryComponent,
        DossierEntrySummaryComponent,
        DossierHistoryComponent,
        DossierLabComponent,
        DossierMedicationComponent,
        DossierMiscComponent,
        DossierPhysicalComponent,
        DossierPdfComponent,
        PdfViewerComponent,
        BrochureDetailComponent,
        TopbarComponent
    ],

我有一个DossierRoutingModule：

const dossierRoutes = [
  {
    path: '',
    component: DossierComponent,
    canActivate: [AuthGuard],
    children: [
      {path: '', redirectTo: 'voorgeschiedenis', pathMatch: 'full', CanActivate: [AuthGuard]  },
      {path: 'voorgeschiedenis', component: DossierHistoryComponent, CanActivate: [AuthGuard]  },
      {path: 'lichamelijk', component: DossierPhysicalComponent, CanActivate: [AuthGuard]  },
      {path: 'lab', component: DossierLabComponent, CanActivate: [AuthGuard]  },
      {path: 'overig', component: DossierMiscComponent, CanActivate: [AuthGuard]  },
      {path: 'medicatie', component: DossierMedicationComponent, CanActivate: [AuthGuard]   },
      {path: 'correspondentie', component: DossierCorrespondenceComponent, CanActivate: [AuthGuard]  },
    ]
  },
];

，在app.module.ts中，我删除了dossierModule。但我仍然收到此错误：

compiler.js:215 Uncaught Error: Template parse errors:
Can't bind to 'pdfTitle' since it isn't a known property of 'app-pdf-viewer'.

但这怎么可能？因为我在de dossier.module.ts中包含了PdfViewerComponent。

那该如何解决呢？

谢谢

在app.routes.ts文件中，我有这个：

{path: '', redirectTo: '/dossier', pathMatch: 'full'},
  {path: 'dossier', loadChildren: './dossier/dossier.module#DossierModule' },

以及app.module.ts的导入现在看起来像这样：

imports: [
    AdviceModule,
    TrainingModule,
    MeasurementModule,
    SettingsAccountModule,
    ObjectiveModule,
    TodoModule,
    PanelModule,
    EcheqModule,
    SharedModule,
    BrowserModule,
    FormsModule,
    BrowserAnimationsModule,
    AppRoutingModule,
    DragulaModule.forRoot(),
    RouterModule,
    ChartsModule,
    HttpClientModule
  ],

哦，这是个洞：dossier.module.ts：

@NgModule({

    imports: [
        RouterModule,
        CommonModule,
        ReactiveFormsModule,
        DossierRoutingModule,
        PdfViewerModule,
        SharedModule
        ],

    declarations: [
        DossierComponent,
        DossierCorrespondenceComponent,
        DossierCorrespondenceItemComponent,
        DossierEntryComponent,
        DossierEntrySummaryComponent,
        DossierHistoryComponent,
        DossierLabComponent,
        DossierMedicationComponent,
        DossierMiscComponent,
        DossierPhysicalComponent,
        DossierPdfComponent,
        PdfViewerComponent,
        BrochureDetailComponent,
        TopbarComponent
    ],

    exports: [
        DossierComponent,
        DossierCorrespondenceComponent,
        DossierCorrespondenceItemComponent,
        DossierEntryComponent,
        DossierEntrySummaryComponent,
        DossierHistoryComponent,
        DossierLabComponent,
        DossierMedicationComponent,
        DossierMiscComponent,
        DossierNavigationComponent,
        DossierPhysicalComponent,
        DossierPdfComponent,
        PdfViewerComponent,
        BrochureDetailComponent,
        //PdfViewerControlsComponent,
        TopbarComponent
    ],
})

export class DossierModule {}

我的app.routes.ts文件如下：

const routes: Routes = [

    component: AdviceDetailComponent,
    canActivate: [AuthGuard]

  {
    path: 'advies',
    redirectTo: 'advies/huidig',
    pathMatch: 'full',
    canActivate: [AuthGuard]

  {
    path: 'chat',
    component: ChatFullComponent,
    canActivate: [AuthGuard]

  {

    canActivate: [AuthGuard]

    component: EcheqOverviewComponent,
    canActivate: [AuthGuard]

  {
    path: 'echeq/detail/:echeqId',
    component: EcheqProcessComponent,
    canActivate: [AuthGuard]
  },
  {
    path: 'help',
    component: HelpPageComponent,
    canActivate: [AuthGuard]
  },

   {
     path: 'instellingen/organisatie/:id',
     component: SettingsOrganisationDetailComponent,
     canActivate: [AuthGuard],
     pathMatch: 'full'
   },
  {
    path: 'trainingen',
    component: TrainingComponent,
    canActivate: [AuthGuard]
  },
  {
    path: 'doel/:id',
    component: ObjectiveComponent,
    canActivate: [AuthGuard]
  },
   {
     path: 'doelen',
     component: ObjectiveListComponent,
     canActivate: [AuthGuard]
   },
  {
    path: 'trainingen/:training',
    component: TrainingDetailComponent,
    canActivate: [AuthGuard]
  },
  {
    path: '**',
    redirectTo: '/dashboard',
    pathMatch: 'full'
  }
];

@NgModule({
  imports: [
    RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules})
  ],
  exports:[RouterModule]
})

export class AppRoutingModule {}

，例如settingsRoutingModule看起来像这样：

const settingsRoutes: Routes = [

  {
    path: '',
    component: SettingsNavigationComponent,
    canActivate: [AuthGuard],
    children: [
     {path: '', redirectTo: 'account', pathMatch: 'full', canActivate: [AuthGuard] },
     {path: 'account', component: SettingsAccountComponent, canActivate: [AuthGuard] },

     {path: 'apparaten' , component: SelfcareComponent, canActivate: [AuthGuard] },
     {path: 'apps' , component: SettingsAppsComponent, canActivate: [AuthGuard] },
     {path: 'indicatiepermissies' , component: SettingsIndicatorPermissionsComponent, canActivate: [AuthGuard] },
     {path: 'algemeen' , component: SettingsGeneralComponent, canActivate: [AuthGuard] },
     { path: 'algemeen', component: SettingsGeneralComponent, canActivate: [AuthGuard] },
     {path: 'log' , component: SettingsLogComponent, canActivate: [AuthGuard] },
    ]
   },
];


@NgModule({
  imports: [RouterModule.forChild(settingsRoutes)],
  exports: [RouterModule]
})

export class SettingsRoutingModule {}

但是，如果我从app.module.ts文件中删除SettingsAccountModule。应用程序中断。

例如，我在app.module.ts中执行此操作，然后应用程序Angular不再能够找到组件。

imports: [
    AdviceModule,
    TrainingModule,
    MeasurementModule,
   // SettingsAccountModule,
    ObjectiveModule,
    DossierModule,
    TodoModule,
    PanelModule,
    EcheqModule,
    SharedModule,
    BrowserModule,
    FormsModule,
    BrowserAnimationsModule,
    AppRoutingModule,
    DragulaModule.forRoot(),
    RouterModule,
    ChartsModule,
    HttpClientModule
  ],

更新：您需要在引发错误的模块中导入发生故障的组件，还要在ng服务脚本中使用AOT

您需要在导出数组中的模块中添加可重用组件：

@NgModule({

    imports: [
        RouterModule,
        CommonModule,
        ReactiveFormsModule,
        DossierRoutingModule,
        PdfViewerModule,
        SharedModule
        ],

    declarations: [
        DossierComponent,
        DossierCorrespondenceComponent,
        DossierCorrespondenceItemComponent,
        DossierEntryComponent,
        DossierEntrySummaryComponent,
        DossierHistoryComponent,
        DossierLabComponent,
        DossierMedicationComponent,
        DossierMiscComponent,
        DossierPhysicalComponent,
        DossierPdfComponent,
        PdfViewerComponent,
        BrochureDetailComponent,
        TopbarComponent
    ],

    exports: [
        DossierComponent,
        DossierCorrespondenceComponent,
        DossierCorrespondenceItemComponent,
        DossierEntryComponent,
        DossierEntrySummaryComponent,
        DossierHistoryComponent,
        DossierLabComponent,
        DossierMedicationComponent,
        DossierMiscComponent,
        DossierNavigationComponent,
        DossierPhysicalComponent,
        DossierPdfComponent,
        PdfViewerComponent,
        BrochureDetailComponent,
        //PdfViewerControlsComponent,
        TopbarComponent
    ],
})

export class DossierModule {}
