以下脚本:
from selenium import webdriver
wd = webdriver.Firefox()
或者
from selenium import webdriver
wd = webdriver.Chrome()
在我的 Windows 7 机器上几乎总是失败,产生以下堆栈跟踪:
Traceback (most recent call last):

Chrome 也一样(显然,...\webdriver\chrome\webdriver.py 除外)。这种行为非常一致,尽管在极少数情况下重新尝试在同一个 Python 会话中打开 webdriver 将允许 Selenium 成功打开浏览器,并且(据我所知)从那里开始正确运行。
在我的 Linux 机器上没有观察到这种行为,它在同一网络上;任何打开 webdriver 的尝试都可以正常工作。
我很难过,我通过 Google 发现的所有套接字超时问题都与尝试访问网页有关,而不仅仅是创建新的 webdriver 对象。我可以提供解决此问题所需的任何其他信息。
这是您问题的答案-
当你一起工作Selenium 3.4.3
,chromedriver v2.30
,geckodriver v0.17.0
,Google Chrome 59.0
并Mozilla Firefox 53.0
通过Python 3.6.1
您可以考虑以下选项:
要初始化,chromedriver
您可以考虑提及chromedriver
throughexecutable_path
参数的绝对路径,并另外指定/使用该chrome_options
参数来配置所需的浏览器属性,如下所示:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path="C:\\Utility\\BrowserDrivers\\chromedriver.exe")
driver.get("https://www.google.co.in")
要初始化,geckodriver
您可以考虑提及geckodriver
throughexecutable_path
参数的绝对路径,并另外指定/使用该firefox_binary
参数来配置所需的浏览器,如下所示:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
binary = FirefoxBinary('C:\\Program Files\\Mozilla Firefox\\firefox.exe')
caps = DesiredCapabilities().FIREFOX
driver = webdriver.Firefox(firefox_binary=binary, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
driver.get('https://stackoverflow.com')
