我在使用 Grid 上的远程 Webdriver 功能（1 个 Linux 集线器和 1 个带有 Firefox 和 Chrome 的 Linux 节点）启动 Chrome 的 Cucumber 测试时遇到问题。 Firefox 测试进行得很顺利，但 Chrome 返回以下错误：
unknown error: Chrome failed to start: exited abnormally
(Driver info: chromedriver=2.2,platform=Linux 3.2.0-23-generic-pae x86) (WARNING: The server did not provide any stacktrace information)
java.util.concurrent.ExecutionException: org.openqa.selenium.WebDriverException: java.lang.reflect.InvocationTargetException
Command duration or timeout: 20.67 seconds
Build info: version: '2.30.0', revision: 'dc1ef9c', time: '2013-02-19 00:15:27'
System info: os.name: 'Linux', os.arch: 'i386', os.version: '3.2.0-23-generic-pae', java.version: '1.7.0_25'
Driver info: org.openqa.selenium.chrome.ChromeDriver (org.openqa.selenium.WebDriverException) (Selenium::WebDriver::Error::UnknownError)
浏览器初始化为：
$profile = Selenium::WebDriver::Chrome::Profile.new
$profile['download.prompt_for_download'] = false
$profile['download.default_directory'] = downloads_path
capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
platform: "Linux",
version: "",
"chrome.profile" => $profile)
browser = Watir::Browser.new(
:remote,
:url => 'http://aut.theurl.net:4444/wd/hub',
:desired_capabilities => capabilities)
更多信息：
- 我尝试了 chromedriver 版本 2.3 和 2.2 以及 selenium-server-standalone 2.35 和 2.3，但未成功。
- 虽然终端，chromedriver 启动成功，所以路径似乎没问题。
Chrome 似乎在远程节点上启动但立即失败。我有点没有想法，所以欢迎任何想法或指导。
提前致谢！
=====================================
更新：添加了更多控制台日志信息。也许这里有更多信息，但我看不到任何有价值的东西。
