亚马逊 EC2 实例上的 pyvirtualdisplay
pyvirtualdisplay on Amazon EC2 instance
我正在尝试 运行 亚马逊 EC2 上的硒。我正在使用 pyvirtualdisplay 作为 xvfb 包装器。我 运行 在 python.
中执行以下命令
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()
到目前为止一切正常。
但是当我这样做时：
driver = webdriver.Firefox()
我收到这个错误：
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__

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了所有可能的事情之后，对我有用的一件事就是这个。

正如答案所说：
它正试图这样加载 wring pixman。删除/usr/local/lib/libpixman-1.so.0再试一次，它会让Xvfb使用带有这个符号的分发pixman库。
