./src/javascripts/moda-ng2/src/app/services/banner.spec.ts中的错误 找不到模块：错误：无法解析/ home / denimuser / Documents / maya / src / javascripts / moda-ng2 / src / app / services中的'file'或'directory'./banner.component @ ./src/javascripts/moda-ng2/src/app/services/banner.spec.ts 4：25-54 webpack：无法编译。
但是这个测试运行 - 的 simple.spec.ts
import {} from 'jasmine';
describe('Meaningful Test', () => {
it('1 + 1 => 2', () => {
expect(1 + 1).toBe(2);
});
});
所以banner.spec.ts中的这个语句import { BannerComponent } from './banner.component';无法加载“BannerComponent”
我做错了什么。请帮助：）
答案 0 :(得分：0)
在文件选项下的karma配置中，您只包含了规范 添加src文件的输入路径也是因为files选项告诉karma在浏览器中加载文件所以我认为这是主要问题。试试这个。
答案 1 :(得分：0)
最后通过添加
来实现它 resolve: {
extensions: ['', '.js', '.ts', '.html']
},
到webpack的测试配置！
该死!!一天过得怎么样！ ： - /
