Question

我正在尝试截取一些网页的屏幕截图。我选择了selenium和firefox。我正在使用xvfb并为显示设置环境变量。

在OS X桌面上没有xvfb的情况下脚本运行正常。但是在服务器上，脚本在发出webdriver.Firefox()后挂起，好像python脚本不再执行一样。在我的进程列表中没有异常被引发并且firefox仍处于活动状态。

设定：

sudo Xvfb :10 -ac
export DISPLAY=:10

test.py

from selenium import webdriver

print 'start'
firefox = webdriver.Firefox()
print 'Hello?'
firefox.quit()
print 'done!'

输出：

start
cursor winks tauntingly

我和Chrome有同样的问题。还尝试了phantomJs闪存叉，这是成功但没有捕获闪存内容。

独立启动firefox给出

请帮忙

谢谢！
