我用量角器+硒与grunt。测试在我的机器（mac）上完全在Chrome和Firefox上运行。但在CENTOS 6.5上，它不适用于Chrome。 Firefox在CENTOS机器上运行。如果我从PATH变量中删除Chromedriver，我会得到相同的错误。所以我知道它不是导致问题的Chromedriver，因为我也在量角器配置文件中指定了它。我怎么知道这是一个硒问题还是一个chromedriver问题？我做了一个“npm install”并且有“chromedriver”：“^ 2.21.2”，“量角器”：“^ 3.3.0”，“selenium-server-standalone-jar”：“^ 2.53.0”，“ webdriver-manager“：在package.json中指定的”^ 10.0.2“。运行grunt命令时会出现什么问题？詹金斯+ Webdriver错误+铬+
我得到的错误是
grunt --ENV=qa --clientName=clientname --device=desktop e2e-test

你有没有找到解决这个问题的方法？我在Jenkins量角器测试中遇到同样的错误。 – JCC
@JCC我搜索了很多这个问题。虽然我还没有找到解决方案，但我发现这个“超级（opt_error）”出现时，它似乎就像Chromedriver没有启动。执行以下操作：在服务器上将Java升级到1.8运行。在我的情况下，这是CENTOS 6.5机器，很遗憾，由于公司政策问题，我们无法升级。这就是说我已经使用的解决方法是让它在Saucelabs上运行。如果你的公司没有得到认证，我会认真推荐购买。我会很快将我的项目发布到Github。我会在这里发表评论。 – writetocynthia
谢谢，我可以通过安装xvfb，无头驱动程序，然后在Jenkins上使用相同的插件来解决此错误。但现在我有其他的错误，这不是。 – JCC
