【问题描述】：

我正在尝试设置一个简单的ng-for 以循环遍历 Angular 的项目列表，但被卡住了。我已经尝试了Angular2 exception: Can't bind to 'ngFor' since it isn't a known native property 中的解决方案（修复缺少#）但没有成功。

EXCEPTION: Template parse errors:
Can't bind to 'ng-forOf' since it isn't a known native property ("<div class="ui link cards">
    <div class="card" [ERROR ->]*ng-for="#project of projects">
        <div class="image">
            <img src="{{project.illustrat"): Projects@1:22
Property binding ng-forOf not used by any directive on an embedded template ("<div class="ui link cards">
    [ERROR ->]<div class="card" *ng-for="#project of projects">
        <div class="image">
            <img src="{"): Projects@1:4

                "name": "project #2"
            }
        ]
    }
}

问题

我该如何解决这个问题？
内部/外部模板均失败（即 templateUrl）

【问题讨论】：

正如其他人所建议的，使用 *ngFor，而不是 *ng-for

标签： ecmascript-6 angular angular2-directives angular2-template

【解决方案1】：

ng-for 在最近的 Angular 版本中不正确。模板已更改为区分大小写。现在应该是ngFor

另见Can't bind to 'ng-forOf' since it isn't a known native property
