组件我从数据库获取数据但无法执行ngFor，请在下面找到错误信息

<!DOCTYPE html>
<html>

<body>
    <div class="row">
        <div class="col-xs-12 col-md-offset-4">
            <table  class="table table-striped">
                <tr *ngFor="category of categoriesInfo" >
                    <td data-title="'Name'">
                        <a>{{category.CategoryName}}</a>
                    </td>
                    <td>
                        <button type="button" class="btn btn-sm">Delete</button>
                    </td>
                </tr>
            </table>
        </div>

    </div>
</body>
</html>

错误信息 我的申请中断了，请你告诉我我做了哪些改变才能使其发挥作用

应用模块 我在我的应用程序中只使用了一个模块

import { Component,OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params } from '@angular/router';
import { CategoriesService } from './categories.component.service';
import { EventsEmitter } from '../../../assets/scripts/services/eventsEmitter';

@Component({
    selector: 'categories',
    templateUrl: 'app/components/admin/categories/categories.component.html',
    styleUrls: ['app/components/admin/categories/categories.component.css'],
    providers: [CategoriesService]
})
export class CategoriesComponent {
    categoriesInfo: any;

    constructor(
        private router: Router,
        private categoriesService: CategoriesService,
        private eventsEmitter: EventsEmitter) {
    }

    ngOnInit() {
        this.getCategoriesResource();
    }

    getCategoriesResource() {
        this.categoriesService.getCategoriesResource()
            .subscribe(response => {
                debugger;
                this.categoriesInfo = response;
            },
            error => {
                this.eventsEmitter.broadcast('Error', 'Error Occured');
            });
    }


}

Answer 1

您只是错过let

中的*ngFor关键字

<tr *ngFor="let category of categoriesInfo" >

Answer 2

您需要为指令CommonModule导入*ngFor并使用let，因为garth74说：

import { CommonModule } from '@angular/common';


@NgModule({
  imports: [ CommonModule ],  // use 'imports' not 'import', s is mandatory
  ...
})

* ng不适用于html表（角度2）
