我正在尝试使用Selenium和Xvfb在Amazon EC2环境中使用Python以无头模式连接到Firefox。我已经尝试了大部分工作组合但没有结果。
from xvfbwrapper import Xvfb
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium import webdriver
import os
try:
vdisplay = Xvfb()
vdisplay.start()
file_entity = open("/home/ubuntu/downloads/fflog.txt", 'wb')
temp_folder = '/home/ubuntu/downloads/ffData'
dir =''
if not os.path.exists(temp_folder):
dir = os.makedirs(temp_folder)
ffProfile = webdriver.FirefoxProfile(profile_directory=temp_folder)
binary = FirefoxBinary(log_file= file_entity)
driver = webdriver.Firefox(firefox_binary=binary)
finally:
vdisplay.stop()
我得到的例外：
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 64, in __init__
self.binary, timeout),

raise WebDriverException("**Can't load the profile. Profile " selenium.common.exceptions.WebDriverException:** **Message: Can't load the profile. Profile Dir: %s If you specified a log_file in the FirefoxBinary constructor, check it for details.**
这是来自FirefoxBinary（fflog.txt）的日志数据：
