Ruby on rails 尝试使用chromedriver运行chrome时出错

我试图从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chromedriver版本-v2.9.248304

有人能指出我是不是做错了什么吗。不知道该怎么办谷歌似乎帮不上忙，我是ruby和脚本的新手

当我尝试启动chrome时，出现以下错误-

Selenium::WebDriver::Error::UnknownError: unknown error: Chrome failed to start: exited abnormally

根据您的问题，可能有两个原因

在路径变量中未正确设置Chromedriver或

缺少显示参数环境变量

请浏览本帖，了解显示参数可能会对您有所帮助：

问题是我的机器没有显示驱动程序，所以当我尝试运行chrome时，它失败了。还有一件事我也尝试了headless使用chrome驱动程序，但问题是我没有足够的权限让headless gems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

如果有人对此有任何其他疑问，您可以在此处向我发送个人消息，或只是对此发表评论，然后尝试回复。

请告诉我如何给出显示参数，我将尝试此方法。由于选项1不适用于我，我已经为后面提到的ChromeDriver设置了路径变量，您可以通过

export DISPLAY=：0设置变量值，这也不起作用。我已经在环境变量中添加了DISPLAY。你能告诉我如何给出DISPLAY参数吗？我会试试这个。由于选项1不适用于我，我已经为后面提到的ChromeDriver设置了路径变量，您可以通过
