模板解析错误 - >无法绑定到'ngforOf'，因为它不是'ion-item'的已知属性

Question

我从web服务已经和我的html页面中获取数据我想呈现此数据。我用*ngfor遍历数据：

<ion-list> 
    <ion-item *ngfor="let item of items"> 
     {{item.Problem}} 
    </ion-item> 
</ion-list> 

，但它返回：

Uncaught Error: Template parse errors: 
Can't bind to 'ngforOf' since it isn't a known property of 'ion-item'. 
1. If 'ion-item' is an Angular component and it has 'ngforOf' input, then verify that it is part of this module. 
2. If 'ion-item' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. 
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. (" 
    <ion-list> 

     <ion-item [ERROR ->]*ngfor="let item of items"> 

      {{item.Problem}} 
"): ng:///AppModule/[email protected]:18 
Property binding ngforOf not used by any directive on an embedded template. Make sure that the property name is spelled correctly and all directives are listed in the "@NgModule.declarations". (" 
    <ion-list> 

     [ERROR ->]<ion-item *ngfor="let item of items"> 

      {{item.Problem}} 
"): ng:///AppModule/[email protected]:8 

我查了ngfor语法已经，如何解决这个问题？

Answer 1

应该*ngFor

<ion-item *ngFor="let item of items">
