我在docker容器中运行了E2E测试。在周五的硒元素/节点铬元素更新之后，它将不再工作。我试过使用旧版本的selenium/nodechrome，但它不起作用。我对码头集装箱等的经验很少
谷歌浏览器80.0.3987.106<-运行命令获得的信息谷歌chrome——chromediver-80.0.3987.106<-信息获取自/opt/selement/文件夹。
以下是我的Dockerfile的样子：

构建似乎很顺利，没有任何问题，但当尝试运行测试时，我收到以下错误消息：

意味着ChromeDriverv80.0无法启动/生成新的浏览上下文，其中Docker镜像适用于Chrome(80.0(。
根据讨论，WebDriver 80.0.3987.16无法在Linux上打开Chrome@triciac提到，ChromeDriverv80.0的实现按以下顺序查找Chrome：
- locations->push_back(base:：FilePath("/usr/local/sbin"((
- locations->push_back(base:：FilePath("/usr/local/bin"((
- locations->push_back(base:：FilePath("/usr/sbin"((
- locations->push_back(base:：FilePath("/usr/bin"((
- locations->push_back(base:：FilePath("/sbin"((
- locations->push_back(base:：FilePath("/bin"((
- locations->push_back(base:：FilePath("/opt/google/chrome"((；//最后一次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，这是为了更容易配置Chrome二进制文件的名称，但也意外更改了搜索顺序。
ChromeDriver团队已更新ChromeDriver，以通过此次修订/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:WebDriverException中找到详细的讨论：Chrome无法启动：由于谷歌Chrome不再运行而崩溃，因此ChromeDriver假设Chrome已崩溃
