Angular formControl问题：Can't bind to 'formControl' since it isn't a known property of 'input'

问题：使用Angular 表单时，报错：Can't bind to 'formControl'  since it isn't a known property of 'input'

 

 解决办法：

在使用form表单时，如果用到了form-group与formControlName，在相应的module中的import引入的不仅仅有FormsModule，还要引入ReactiveFormsModule
