我也尝试过使用Python脚本，但是我也遇到了同样的错误。
#!/usr/bin/env python
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()

尝试使用webdriver.Chrome（）
