我正在尝试使用 Jasmine 设置 Karma 以测试我的 Angular2 应用程序。Karma 无法在规范文件中附加导入的扩展名。例如，我的规范文件有import {TileComponent} from './tiles.component'; 当我运行 Karma 时出现以下错误：http://localhost:9876/base/wwwroot/app/tiles/tiles.component 404 (Not Found) 如果我尝试转到此链接并在最后手动附加 js，它将加载我的文件。

业力.conf.js：

module.exports = function (config) {

    var appBase = 'wwwroot/app/';
    var appAssets = '/base/app/';

问题是我两次导入 system.config.js。我从 karma.conf.js 文件中删除了导入。我还做了一些小的路径更改。
