我正试图在Amazon EC2上运行硒。我使用pyvirtualdisplay作为xvfb包装。我在python中运行以下命令。Amazon EC2实例上的pyvirtualdisplay
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()
一切都很好，直到现在。
但是当我做：
driver = webdriver.Firefox()
我得到这个错误：
Traceback (most recent call last):
