python-2.7 - Selenium Pyvirtualdisplay 在启动时挂起

Question

我有一个 Selenium 测试，我试图在我的 ubuntu 服务器上 headless (headless)运行。它使用 pyvirtualdisplay 和 xephyr。尽管该脚本在我的本地系统中运行良好，但当我在服务器中运行它时它会挂起。我尝试清除内存并重新启动服务器。但没有运气。该脚本看起来像这样:

from selenium import webdriver
from pyvirtualdisplay import Display

display = Display(visible=0, size=(1366, 768))
display.start()
driver = webdriver.Firefox()
driver.set_window_size(1366, 768)
driver.get ("http://www.google.com/")

有什么帮助吗？

好吧，终于搞定了。

sudo apt-get install xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic

sudo apt-get -y install x-ttcidfont-conf cabextract ttf-mscorefonts-installer

sudo apt-get -y install x-ttcidfont-conf

sudo dpkg-reconfigure x-ttcidfont-conf

选择freetype，之后，当我执行xvfb-run firefox时然后我开始收到这样的错误:

Xlib:  extension "RANDR" missing on display ":99".

(firefox:4691): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
//bin/dbus-launch terminated abnormally without any error message

(firefox:4691): LIBDBUSMENU-GLIB-WARNING **: Unable to get session bus: Error spawning command line `dbus-launch --autolaunch=c4970e12ff5496da09501f87000001fe --binary-syntax --close-stderr': Failed to execute child process "dbus-launch" (No such file or directory)

(firefox:4691): GConf-WARNING **: Client failed to connect to the D-BUS daemon:

要解决此问题，请执行以下操作:

apt-get install dbus-x11
