Question

我有一个Angular 4 / Material项目，正在使用Visual Studio Code。该项目使用angular / cli

设置

我已经开始使用Karma和Jasmin编写一些单元测试。设置全部由angular / cli完成。

现在我想调试我的测试。

运行＆＃34; ng test＆＃34;给出了一些错误。尝试通过在代码中设置断点来调试这些错误，没有结果。

使用谷歌我发现了很多关于如何配置Karma和VSC的建议，但他们都没有帮助过我。我的猜测是这是一个依赖于版本的问题。

基于我的设置，任何人都可以帮助我吗？

如果我发布配置文件，可能会有人看到一些问题。

我的解决方案是创建一个具有最新和最大角度cli的新角度。它像舞蹈一样工作，然后我将配置文件复制到我的真实项目中。
