typescript - ChromeDriver 在启动后失败并出现以下错误

Question

我正在尝试在 azure devops 的管道中运行量角器 e2e 测试，但它在加载 chrome webdriver 后一直失败。我在本地运行相同的脚本并且工作正常，但在 azure devops 上它失败了。谁能帮我理解它为什么失败？

代理规范：ubuntu-18.04 代理池：Azure Pipelines 节点版本：10.x 使用 Azure Repos

并使用自定义更新根文件夹和 ./node_modules/protractor 中的 webdriver-manger

一旦使用运行 e2e 测试的 npm 完成此操作，但在直接使用 chrome 驱动程序之后它就会失败。

我知道那里有很多解决方案，但没有什么对我有用。下面提到了我到目前为止尝试过但一直失败的解决方案

1. 添加“args”：[“--disable-dev-shm-usage”]，“args”：[“--no-sandbox”]。
2. 尝试并使用终端命令安装 Chrome，以确保它安装在 Rakesh 在此链接中提到的正确路径中。
3. 尝试将 webdriver-manager 版本降级到 2.38。
4. 尝试在 firefox 浏览器中运行（在本地运行，但在 azure devops 中运行）。
5. 尝试将 directConnect 设置为 false 并给出 selenium 地址
6. 也在隐身模式下运行它
7. 尝试在本地和 devops 上失败的无头模式下运行
8. 还尝试运行示例代码，但也不断抛出错误。

我还应该做些什么来解决这个错误？谁能帮忙
