我正在使用带有量角器+硒的gulp。功能测试在我的机器（mac）上完美地在 Chrome 上运行。但在 CENTOS 7（docker 容器）上，它不适用于 Chrome。如果我从 PATH 变量中删除 Chromedriver，我会得到同样的错误。我怎么知道这是硒问题还是 chromedriver 问题？我做了一个“npm install”并有“chromedriver”：“^2.21.2”，“protractor”：“^3.3.0”，“selenium-server-standalone-jar”：“^2.53.0”， webdriver-manager": "^10.0.2" 在 package.json 中指定。运行 gulp 命令时有什么问题？
这是我的错误日志：
