angular There is no directive with exportAs set to ngModel

当使用 ngModel 是报错

angular There is no directive with exportAs set to ngModel

代码:

<input name="username" #username="ngModel" />

解决:

1、首先在app.module.ts中引入FormsModule

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

并在NgModule的imports中引入 FormsModule

2、添加[(ngModel)]

<input name="username" [(ngModel)]="username" #username="ngModel" />
