angular报错:Cannot assign to a reference or variable

错误代码:

<input #manufacturerId="ngModel" id="manufacturerId" name="manufacturerId" [(ngModel)]="manufacturerId" [disabled]="!isEdit">

报错原因: 同时声明了#manufacturerId="ngModel" 和[(ngModel)]="manufacturerId"。

解决方案，将其中一个参数名改掉即可，比如我将前面的manufacturerId改成manufacturerIdInput。
