在Linux Jenkins CI服务器上使用Xvfb的Firefox无头测试自动化

我正在尝试使用Xvfb和firefox来运行测试自动化无头。 但是，我在启动xvfb时收到以下消息。

XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6 _XSERVTransOpen: transport open failed for inet6/cvms1247:99 _XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6 Initializing built-in extension Generic Event Extension Initializing built-in extension SHAPE Initializing built-in extension MIT-SHM Initializing built-in extension XInputExtension Initializing built-in extension XTEST Initializing built-in extension BIG-REQUESTS Initializing built-in extension SYNC Initializing built-in extension XKEYBOARD Initializing built-in extension XC-MISC Initializing built-in extension SECURITY Initializing built-in extension XINERAMA Initializing built-in extension XFIXES Initializing built-in extension RENDER Initializing built-in extension RANDR Initializing built-in extension COMPOSITE Initializing built-in extension DAMAGE Initializing built-in extension MIT-SCREEN-SAVER Initializing built-in extension DOUBLE-BUFFER Initializing built-in extension RECORD Initializing built-in extension DPMS Initializing built-in extension Present Initializing built-in extension X-Resource Initializing built-in extension XVideo Initializing built-in extension XVideo-MotionCompensation Initializing built-in extension SELinux Initializing built-in extension GLX 

然后我尝试了以下命令：

  Xvfb :001 -nolisten inet6 export http_proxy=http-proxy.nwie.net:8080 

以下消息消失了。

  XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6 _XSERVTransOpen: transport open failed for inet6/cvms1247:99 _XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6 

无头的用法：

  if OS::windows? || ENV['PhantomJS'] == 'true' browser = Selenium::WebDriver.for :remote, url: 'http://localhost:8001' elsif OS::linux? require 'headless' headless = Headless.new headless.start browser = Selenium::WebDriver.for :firefox at_exit do browser.close headless.destroy end else raise 'Unknown OS' end 

环境：

  Ruby: 1.9.3 Jenkins: 1.58 Selenium webdriver: 2.53 headless: 2.3.1 Xvfb: yum install xorg-x11-server-Xvfb firefox: 33.0 Linux: 2.6.32-573.12.1.el6.x86_64 

我错过了什么？

没有错误，或者您忘记包含它。

您发布的示例输出不包含单词“error”。

您可能会被“无法打开inet6的套接字”消息所误导。 对我而言，这看起来像是xv服务器不会使用ipv6的信息性消息。 之后的初始化成功，所以很可能ipv4工作正常或者其他什么。
