解决Angular里面报错：error NG8002: Can‘t bind to ‘ngModel‘ since it isn‘t a known property of ‘input‘._ngModel

以上是报错内容（[(ngModel)]双向绑定失效）

解决办法：在module.ts中添加

import { FormsModule } from '@angular/forms';

imports: [

FormsModule,//不加入FormsModule就会报错[(ngModel)]双向绑定失效

...

],

解决Angular里面报错：error NG8002: Can‘t bind to ‘ngModel‘ since it isn‘t a known property of ‘input‘._双向绑定_02

这样就可以使用[(ngModel)]双向绑定了
