亚马逊EC2实例上的pyvirtualdisplay

Question

我正在亚马逊EC2上运行selenium。我使用pyvirtualdisplay作为xvfb包装器。我在python中运行了以下命令。

from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()

到现在为止一切都很好。

但当我这么做的时候

driver = webdriver.Firefox()

我知道这个错误：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.6/site-   packages/selenium/webdriver/firefox/webdriver.py", line 59, in __init__
self.binary, timeout),
File "/usr/lib/python2.6/site-packages/selenium/webdriver/firefox/extension_connection.py", line 47, in  __init__
self.binary.launch_browser(self.profile)
File "/usr/lib/python2.6/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 66, in launch_browser
self._wait_until_connectable()
File "/usr/lib/python2.6/site- packages/selenium/webdriver/firefox/firefox_binary.py", line 100, in _wait_until_connectable
raise WebDriverException("The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser   appears to have exited before we could connect. If you specified a    log_file in the FirefoxBinary constructor, check it for details.

在互联网上花了很多时间寻找解决方案并尝试每一件可能的事情之后，有一件事对我有效。

正如答案所述：

它正试图加载拧断像素所以。删除/usr/local/lib/libspinman-1.so.0，然后再试一次，它将使Xvfb使用具有此符号的分发像素库。
