升级到 ChromeDriver v80 和 Chrome v80 后，Chrome 无法在使用 Selenium 的 docker 容器中启动

Question

我在 docker 容器中运行 E2E 测试。 在周五更新 selenium/node-chrome 之后，它将不再起作用。 我曾尝试使用旧版本的 selenium/node-chrome 但它不起作用。 我对 docker 容器等的经验很少。

谷歌浏览器 80.0.3987.106 <- 信息获取运行命令 google-chrome --version chromedriver-80.0.3987.106 <- 信息来自 /opt/selenium/ 文件夹。

这是我的 Dockerfile 的样子：

构建似乎运行良好，没有任何问题，但是在尝试运行测试时，我收到以下错误消息：

这个错误信息...

[13:51:36] E/launcher - unknown error: Chrome failed to start: crashed.

...暗示ChromeDriver v80.0无法在Chrome (80.0) 的 Docker 映像中启动/生成新的浏览上下文。

根据讨论WebDriver 80.0.3987.16 can't open Chrome on Linux @triciac 提到， ChromeDriver v80.0的实现按以下顺序查找Chrome ：

1. 位置->push_back(base::FilePath("/usr/local/sbin"));
2. 位置->push_back(base::FilePath("/usr/local/bin"));
3. 位置->push_back(base::FilePath("/usr/sbin"));
4. 位置->push_back(base::FilePath("/usr/bin"));
5. 位置->push_back(base::FilePath("/sbin"));
6. 位置->push_back(base::FilePath("/bin"));
7. 位置->push_back(base::FilePath("/opt/google/chrome")); // 最后尝试使用默认安装位置。

@johnchen 证实，Linux 上的二进制搜索顺序被r708243意外更改，旨在使配置 Chrome 二进制文件的名称更容易，但也意外更改了搜索顺序。

ChromeDriver团队已更新ChromeDriver以通过此修订/ 提交解决此问题。

解决方案

上述解决方案可用于：

• ChromeDriver v80.0.3987.106
• ChromeDriver v81.0.4044.20

临时解决方案

一个临时解决方案是使用binary_location属性，您可以在Selenium 中找到详细讨论：WebDriverException:Chrome failed to start: crashed as google-chrome is no longer running so ChromeDriver is假设 Chrome has crashed
