嗨〜我是Angular2的初学者。
当我使用＆＃34; ANGULAR 2 UI FRAMEWORK＆＃34;作为http://www.angulartypescript.com/angular-2-ui-framework/
我也在我的反应形式中使用了datepicker。 我在下面有错误。
py -3 source.py
我将在下面向您展示我的代码。 的 app.module

另外，添加datepicker的附加基本代码 的 datepicker.module.ts

这是我的项目结构。 enter image description here
所以， 我想知道我的代码有什么问题， 我怎样才能解决这个问题以阻止我的挖掘..
答案 0 :(得分：3)
您需要导入：
import { DatepickerModule } from 'ng2-bootstrap';
@NgModule({
imports: [
DatepickerModule.forRoot()
]
});
