angular - 无法绑定(bind)到指令 ('appHasAccess' )，因为它不是 'input' 的已知属性

Question

我创建了一个自定义属性指令库包并将其安装到 myProject 中，当我尝试使用此自定义指令时会引发错误。

ERROR Error: Uncaught (in promise): Error: Template parses errors: Can't bind to 'appHasAccess' since it isn't a known property of 'input'.

我使用的代码如下:

all possible try I have done. any have an idea how I resolve this.

<强>1。指令:HasAccessDirective.ts

@Directive({
  selector: '[appHasAccess]',
})

export class HasAccessDirective {

accessDetail = { 'a': 1 }
 @Input('appHasAccess') set appHasAccess(accessDetail: any) {
    // Based on right control enable/disable
    this.eleRef.nativeElement.disabled = this.appRights.hasRights(accessDetail);
}
constructor(private eleRef: ElementRef,
    private appRights: MyService) { }
}

<强>2。模块:DigiUserRightsModule.ts

   @NgModule({
        declarations: [
            HasAccessDirective
        ],
        imports: [
            CommonModule,
            HttpClientModule,
        ],
        exports: [
            HasAccessDirective
        ],
        providers: [UserRightsService]
    })

export class DigiUserRightsModule {
    static forRoot(): ModuleWithProviders {
        return {
            ngModule: DigiUserRightsModule,
            providers: [UserRightsService]
        };
    }
}

我做了以下更改以使其正常工作。我将指令模块注入(inject)到我的用户模块而不是应用程序模块中。用户模块在其加载的路线上延迟加载并且工作正常。

• 在用户模块中设置我的指令包模块:

  import { NgModule }      from '@angular/core';       
  
  @NgModule({
     declarations: [],
     imports: [
         DigiUserRightsModule.forRoot()
     ],
     providers: []
  })
  
  export class UserModule {}
