我一直在使用 Selenium Web Driver 开发（在我的 Mac OSX 上）以进行一些抓取，但我需要将脚本移动到无头 Linux 服务器。
通过一些研究，似乎我需要在无头服务器中使用PyVirtualDisplay来simulate启动 Selenium 浏览器。下面是我的代码和我得到的错误。
代码：（来源）
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(800, 600))
display.start()
# now Firefox will run in a virtual display.
# you will not see the browser.
browser = webdriver.Firefox()
browser.get('http://www.google.com')
print browser.title
browser.quit()
display.stop()
我得到的错误：
