我的配置js看起来像下面：

          //to the webdriver instance.

2016-10-13： ChromeDriver v2.24已发布支持Chrome v52-54。 (感谢@Anton)

2016-08-16：Chrome Dev渠道最近的一个更新引入了一个错误，阻止ChromeDriver正常启动。刚刚解决了同样的问题，我建议备份您的数据，并恢复到Chrome的测试版或稳定版发布版本。有关安全切换的更多详细信息，请参阅Chrome Release Channels。

或者，切换到Dev版本的ChromeDriver也应该解决这个问题。从closed issue在chromedriver项目：

There are some Devtool changes in Chrome dev channel v54 which is not currently supported in Chromedriver stable v2.23.
You may want to use dev version of Chromedriver which has the fix. It can be downloaded from chromedriver…/continuous/….zip
