我是AngularJs 2的新手我正在尝试NgFor工作,但我有这个错误,我无法弄清楚出了什么问题:

skills.template.html

<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
    <div class="skills-container">
        <div *ngFor="let item of [0,1,3,4,5];">Try</div>
    </div>
</div>

skills.compontent.ts

import { Component } from '@angular/core';
import { OnInit } from '@angular/core';
import {Candidate} from "../../../../models/Candidate";
import {Input} from '@angular/core';
import {NgbModal, ModalDismissReasons} from '@ng-bootstrap/ng-bootstrap';
@Component({
  selector: 'skills',
  templateUrl: 'skills.template.html',
  providers:[NgbModal]
})
export class skillsComponent implements OnInit {
  @Input() selectedCandidate:Candidate;


  constructor(private modalService:NgbModal){ }

  ngOnInit(){}

  launchSkillsModal(e:any, content:any){
    const modalRef = this.modalService.open(content);
    e.preventDefault();
  }

}

我只是尝试一个简单的循环,但我得到了

 main.bundle.js:6017Error: Template parse errors:(…)(anonymous function) @         main.bundle.js:6017ZoneDelegate.invoke @ zone.js:232Zone.run @ zone.js:114(anonymous function) @ zone.js:502ZoneDelegate.invokeTask @ zone.js:265Zone.runTask @ zone.js:154drainMicroTaskQueue @ zone.js:401

答案 0 :(得分:0)

似乎您正在使用older Angular 2版本,因为组件元数据中的providers已被弃用。在您的情况下,它可以使用较旧的语法#item而不是let item

*ngFor="#item of [0,1,3,4,5];"

虽然我强烈建议您将角度版本更新到最新版本(2.4.1)
