运行测试时出现随机 Karma PhantomJS 脚本错误

Question

我有一个 gulp 任务，它使用 karma 测试运行器为 angular 运行 jasmine 单元测试。一段时间以来，我一直Script Errors在我的 Jenkins CI 系统中随机获取这些信息，因此，测试失败了。这些是在我添加了 29 个单元测试，总共 160 个单元测试（相当少）之后开始的。他们没有显示任何失败。他们显示错误

在我的本地机器上，有时会发生，有时不会。但是在我使用 docker 运行测试的 Jenkins CI 中，它总是失败并出现此脚本错误。并且此脚本错误在任何测试后随机出现，因此无法准确确定导致此错误的代码。在本地使用 docker，测试也通过了。但是在 CI 中，无论如何它总是失败，并且它失败了，Script Error.因为我删除了从外部脚本/任何 $watch 或 $window 相关测试代码中提取的任何代码。这些解决方案都没有帮助我。这些是在 OPEN Github 问题https://github.com/karma-runner/karma/issues/1268 中提出的

我真的需要快速解决这个问题。github 问题仍然悬而未决，这意味着它还没有解决，但我的项目如果不让它工作，基本上是没用的。请帮忙！
