我遇到了令人困惑的错误，实际上我不知道如何解决这样的库问题，我尝试生成我的 cypress 测试用例以向 mochawesome 报告，下面是我的 package.json 安装文件

{
"devDependencies": {
    "cypress": "^3.1.5",
    "mocha": "^6.0.2",
    "mocha-junit-reporter": "^1.18.0",
    "mocha-multi-reporters": "^1.1.7",
    "mochawesome": "^3.1.1",
    "mochawesome-merge": "^1.0.7",
    "mochawesome-report-generator": "^3.1.5"
}

我觉得安装后没有问题， 那我就跑

cypress run --reporter mochawesome

然后测试完成，BOOM之后，我遇到了这样的错误

这是我得到的堆栈跟踪，有人知道如何解决这个问题吗？

最佳答案

我在使用 mocha 版本 6.0.0 或更高版本时遇到了同样的错误。

如果可以，请尝试使用版本5.2.0，直到问题解决，它会正常工作。
