Javascript 是否有解决此错误消息（karma typescript）的方法？

当我运行

karma start

时，我收到以下消息：

未捕获错误：找不到入口点 [/home/sample/sampleproj/test/base.spec.ts]（commonjs.js需要） 在node_modules/karma typescript/dist/client/commonjs.js:13:17

如何解决这个问题

import 'zone.js/dist/zone';
import 'zone.js/dist/long-stack-trace-zone';
import 'zone.js/dist/proxy';
import 'zone.js/dist/sync-test';
import 'zone.js/dist/jasmine-patch';
import 'zone.js/dist/async-test';
import 'zone.js/dist/fake-async-test';
import { TestBed } from '@angular/core/testing';
import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from '@angular/platform-browser-dynamic/testing';

TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting());

在被否决之前，可以先在/home/sample/sampleproj/test/base.spec.ts中显示代码
