Angular 2 Jasmine / Karma Test - 文件应以换行符结尾

Question

我写了一个课，我收到了以下警告：

WARNING in ./src/app/nav/shared/nav.ts
[15, 4]: file should end with a newline

无法为我的生活找出错误。谁知道原因？我的课程文件如下：

// NavToolItem class
export class NavToolItem {
    view: string;
    name: string;
    icon: string;
    type: string;
    link: string;
    order: number;
}

// Array of Menus
export const NAVTOOLITEMARR: NavToolItem[] = [
 {view: 'Dashboard', name: 'menu', icon: 'fa fa-bars fa-3x', type: 'panel', link: '', order: 0},
 {view: 'Dashboard', name: 'search-employee', icon: 'fa fa-search fa-3x', type: 'panel', link: '', order: 0}
 ];
