背景
我正在尝试为Angular 1x应用程序设置测试运行器,但我无法让Karma使用Systemjs和Typescript。
测试用Typescript编写,我们使用Systemjs导入使用ES6模块的文件。大多数文件不使用ES6模块。
我没有像karma-typescript一样使用业力预处理器,而是试图使用Systemjs来转换我的Typescript。这是错误的方式吗?似乎没有发生任何转变!
错误
当我运行karma start
时,脚本在导入打字稿namspace时失败:
import core = myApp.core;
Chrome 52.0.2743 (Windows 7 0.0.0) ERROR
Error: (SystemJS) SyntaxError: Unexpected token import
Evaluating app/scripts/site/core/components/settingsMenu/settingsMenu.spec.ts
Error loading app/scripts/site/core/components/settingsMenu/settingsMenu.spec.ts
这是我的karma.conf.js文件,基于this example。

systemjs config:
System.config({
baseURL: './',
defaultJSExtensions: true
});
答案 0 :(得分:1)
尝试在systemjs config(config.js)中添加transpiler属性:
System.config({
baseURL: './',
defaultJSExtensions: true,
transpiler: 'typescript'
});
