问题描述
背景： 我在配备 Intel Core i5 的 2018 Mac mini 上有一个 macOS 10.15.3 的量角器测试台，它已被用于测试带有夜间 Jenkins 管道的 reactjs 应用程序。它已经运行了几个月。 2021 年 1 月 6 日晚上，测试开始失败，出现未知系统错误，如下面的日志和屏幕截图所示。
这个问题花了我和团队几个小时来解决，我想我会分享我的发现，以防遇到同样问题的人可以不浪费时间找到解决方案。

原因 自从 Google 开始支持 Mac M1 驱动程序以来，无论您使用的是 x86 还是 M1 系统，webdriver-manager 都会以某种方式将 M1 驱动程序视为 macOS 上的默认驱动程序。

-
将 webdriver-manager 升级到 12.1.8：webdriver-manager 团队反应迅速，他们已根据 https://github.com/angular/webdriver-manager/issues/476 发布了一个新版本来解决该问题。简而言之，将 webdriver-manager 升级到 12.1.8 后，问题将自行解决。确保检查您的 package.json、package-lock.json 并在必要时更新它们。
-
如果您因任何原因无法升级 webdriver-manager，只需将 M1 驱动程序替换为 x86 驱动程序即可。它会一直工作，直到您可以升级 webdriver-manager。您可以在 https://chromedriver.storage.googleapis.com/
