python - Selenium firefox 浏览器无法在使用 Python 的 centos 6.0 上运行

Question

如何让 Selenium 在 Centos 6.0 上工作？我收到以下错误。我在 python 2.6 上使用 selenium 2.31.0

yum install ImageMagick ImageMagick-perl  xorg-x11-server-Xephyr Xvfb firefox
sudo yum -y install python-imaging
sudo easy_install pyvirtualdisplay
sudo easy_install selenium

from pyvirtualdisplay import Display
from selenium import webdriver
import time
import argparse
import os
display = Display(visible=0, size=(800, 600))
display.start()
browser = webdriver.Firefox()

对于 python 2.7，selenium 需要安装 pip:

/usr/bin/python2.7 -m pip install --user selenium

在你的 python 2.6 上试试这个。它适用于 Red Hat 6 和 Centos 6。

为了避免调用可执行文件时出现路径问题，您也可以使用此选项:

driver = webdriver.Firefox(executable_path='/bin/geckodriver')
