我正在尝试在 Amazon 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()

到目前为止一切都很好。
但是当我这样做时：

driver = webdriver.Firefox()

我收到此错误：

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__

在互联网上花了很多时间寻找解决方案并尝试了所有可能的事情之后，对我有用的一件事就是这个。
https://superuser.com/questions/870702/aws-ec2-linux-headless-firefox-issue-xvfb-undefined-symbol-pixman-glyph-cache

正如答案所说：
它正在尝试加载 wring pixman。删除 /usr/local/lib/libpixman-1.so.0 并重试，这将使 Xvfb 使用具有此符号的发行版 pixman 库。
