angular - 即使导入 CalendarModule 后，“p-calendar”也不是已知元素错误

Question

即使在导入 CalendarModule 后，在 angular2 中使用 p-calendar 时也会出现以下错误。

从“../../../vendor/primeng/components/calendar/calendar”导入{CalendarModule}；

    Uncaught Error: Template parse errors:
'p-calendar' is not a known element:
1. If 'p-calendar' is an Angular component, then verify that it is part of this module.
2. If 'p-calendar' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("
    <div>
        Calendar
        [ERROR ->]<p-calendar [(ngModel)]="todaysDate"></p-calendar>
    </div>

看来您错过了导入CalendarModule在您的应用程序内。您必须导入 CalendarModule在你的AppModule里面来自primeng库并将其注入(inject)到您的 imports 中的AppModule .

import {CalendarModule} from 'primeng/calendar';

@NgModule({
  imports:      [ 
   BrowserModule, 
   FormsModule,
   CalendarModule, //<-- injected module here.
   FormsModule
  ],
  declarations: [ ... ],
  bootstrap:    [ ... ]
})
export class AppModule { }
