如果有人帮助我解决问题，将不胜感激

【问题讨论】：

你用什么命令来得到这个错误？

@BozhinovskiVladimir npm 运行覆盖率

尝试清除 node_modules 并在此之后安装 npm。

@BozhinovskiVladimir 我们在同时从不同的PowerShell提示符（3）多次运行npm命令时面临这个问题。那么，清除 node_modules 不会影响其他两个进程吗？注意：很明显，在一台机器上安排了三个自动化，用于与 Jenkins 的持续集成过程。

我们使用不同的端口来运行每个 karma 配置的命令。会有问题吗？

【参考方案1】：

您的命令concurrently 似乎返回“EXIT_FAILURE”退出代码，这可能是由您的任何 gulp 任务内部的 javascript 错误引起的。因为我不知道这些任务是做什么的，所以我无法真正帮助你。您可以单独运行每个命令以找到返回错误的命令。
