Nativescript 自定义对话框异常

Nativescript custom dialog exception

我正在尝试按照 this example.

在 nativescript (angular 2) 中获取自定义对话框模式弹出窗口

知道为什么在单击“显示”按钮时出现以下异常:

EXCEPTION: No component factory found for DialogContent (d:\npn\qwe\node_modules\@angular\core\bundles\core.umd.js:3462:27)
ORIGINAL STACKTRACE: (d:\npn\qwe\node_modules\@angular\core\bundles\core.umd.js:3467:31)

我在 中找到了解决方案 在您必须添加的主模块中:

@NgModule({
   ....
    declarations: [ DialogContent ],
    entryComponents: [ DialogContent ]
})
