Question

我正在开发一个Angular2应用程序，我有以下组件：

import {Component, OnInit} from '@angular/core';
import {CourseAdminService} from "../shared/course-admin.service";
import {Course} from "../shared/course";

@Component({
  selector: 'app-course-admin-list',
  templateUrl: './course-admin-list.component.html',
  styleUrls: ['./course-admin-list.component.css']
})
export class CourseAdminListComponent implements OnInit {

  courses: Course[] = [];
  keyword = "";

  constructor(private courseAdminService: CourseAdminService) {
  }

  ngOnInit() {
    this.loadMore();
  }

  reset() {
    this.courses = [];
    this.loadMore();
  }

  loadMore() {
    let since: Date = null;
    let before: Date = null;

    let len = this.courses.length;
    if (len > 1000) {
      since = this.courses[0].creationTime;
      before = this.courses[len - 1].creationTime;
    }

    let subscription = this.courseAdminService.get(since, before, this.keyword)
      .subscribe(courses => {
        this.courses = this.courses.concat(courses);
        subscription.unsubscribe();
      });
  }
}

我有以下界面：

export interface Course {
  id: string;
  nameEn: string;
  nameAr: string;
  trainer: string;
  type: string;
  country: string;
  city: string;
  level: string;
  creationTime: Date;
}

这里的问题是当我尝试编译应用程序时（使用angular @ cli）它会给我错误：Property 'creationTime' does not exist on type 'Course'，正如您在上面看到的那样，creationTime属性确实是一个部分的界面。那么有谁能告诉我这里的问题是什么？

事实证明，无论何时我想修改添加新属性甚至创建新界面的界面，我都必须停止ng serve命令并重新运行它。
