Question

我正在尝试从ruby控制台调用chrome。

我正在使用命令 - Watir::Browser.new :chrome

我有红宝石 - 红宝石1.9.3p484

我已经安装了宝石， watir-wedriver 的版本是 - watir-webdriver（0.6.11）

chrome的版本是 - 44.0.2403.157

我有chromedriver版本 - v2.9.248304

如果我在这里做错了，有人会指出。不知道该做什么谷歌似乎没有帮助，我是一个新的ruby和脚本。

当我尝试启动chrome时，我收到以下错误 -

Selenium::WebDriver::Error::UnknownError: unknown error: Chrome failed to start: exited abnormally
(Driver info: chromedriver=2.9.248304,platform=Linux 3.13.0-32-generic x86_64)

Answer 1

根据您的问题，可能有两个原因

Chromedriver未正确设置在PATH变量OR
您缺少DISPLAY参数环境变量。

请仔细阅读这篇文章，了解DISPLAY参数可能对您有所帮助： Selenium web driver DISPLAY variable value

Answer 2

问题是我的机器没有显示驱动程序所以当我试图运行chrome时它失败了。还有一件事我尝试无头也使用镀铬驱动程序，但问题是我没有足够的权限无头宝石运行。因此，更改权限使我的任务变得简单，现在我可以使用ruby运行selenium脚本。
