角度材料:MatDatepicker:未找到 DateAdapter 的提供程序 [英] Angular material: MatDatepicker: No provider found for DateAdapter

问题描述

我正在尝试在 Angular Material 中使用 Datepicker 组件.这是我的 HTML 代码:

I'm trying to use the Datepicker component in Angular Material. Here is my HTML code:

<input matInput [matDatepicker]="picker" placeholder="Choose a date" disabled>
<mat-datepicker #picker disabled="false"></mat-datepicker>

但是，它对我不起作用，并且出现以下错误:

However, it's not working for me and I'm getting the following error:

错误:MatDatepicker:未找到 DateAdapter 的提供程序.

Error: MatDatepicker: No provider found for DateAdapter.

错误消息告诉我，我需要导入 MatNativeDateModule 和 MatDatepickerModule，但我已经这样做了.下面是我从 app.module.ts 导入的代码:

The error message tells me that I need to import MatNativeDateModule as well as MatDatepickerModule but I have done that. Here is my import code below from app.module.ts:

import {
    MatFormFieldModule,
    MatMenuModule,
    MatCheckboxModule,
    MatIconModule,
    MatDatepickerModule,
    MatNativeDateModule
} from '@angular/material';

还有什么我遗漏的吗?

推荐答案

MatDatepickerModule 和 MatNativeDateModule 在导入下并在提供者下添加 MatDatepickerModule

 imports: [
    MatDatepickerModule,
    MatNativeDateModule 
  ],
  providers: [  
    MatDatepickerModule,  
  ],
