在 Angular 9.1.1 中找不到 MatNativeDateModule、MatMomentDateModule

Question

旧的角度/材料具有这两个模块。但是 angular/material 9.1.1 版本没有这两个模块。我得到以下错误。任何人都知道如何导入这两个模块

Uncaught (in promise): Error: MatDatepicker: No provider found for DateAdapter. You must import one of the following modules at your application root: MatNativeDateModule, MatMomentDateModule, or provide a custom implementation.

角 8,9

import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatNativeDateModule } from '@angular/material/core';

Angular 7 及以下

import { MatDatepickerModule, MatNativeDateModule } from '@angular/material';

您需要在导入下导入 MatDatepickerModule 和 MatNativeDateModule 并在提供者下添加 MatDatepickerModule

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