尝试使用 chrome 驱动程序运行 chrome 时出错

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 ruby - ruby 1.9.3p484

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

chrome的版本是-44.0.2403.157

我有 chrome驱动程序版本 - v2.9.248304

如果我在这里做错了什么，有人能指出来吗？不知道该怎么做 google 似乎没有帮助，我是 ruby 和脚本编写的新手。

我在尝试启动时出现以下错误 chrome -

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

根据你的问题，可能有2个原因

Chromedriver 未在 PATH 变量中正确设置或
您缺少 DISPLAY 参数环境变量。

请仔细阅读此 post，它可能对您了解 DISPLAY 参数有用： Selenium web driver DISPLAY variable value

Answer 2

问题是我的机器没有显示驱动程序，所以当我尝试运行 chrome 它失败了。我还使用 chrome 驱动程序尝试过无头的另一件事，但问题是我没有足够的权限让无头宝石运行。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。
