Python Selenium 问题

[LSB]

代码如下

from selenium import webdriver

import time
# 打开浏览器
#driver = webdriver.Chrome()
driver = webdriver.Firefox()
#driver = webdriver.Edge()
# 设置浏览器最大化
driver.maximize_window()
# 设置隐式等待
driver.implicitly_wait(3)
# 打开网页
driver.get("http://www.baidu.com")

出现的错误

三个浏览器都试过了，都是同样的问题，有小伙伴帮看看么

urllib3 怎么安装的？版本不匹配吧，是不是安装了最新版的 urllib3 ，最新版 urllib3 有很多 breaking changes

[beixiao]

驱动按照版本装了吗

[LSB]

@beixiao 按照版本装了，也设置环境变量了

[LSB]

@tulongtou 我降级版本看看

[1d074bfa18d34f6c]

语法没有问题，应该是 Selenium 或者 Webdriver 版本问题，建议卸载重装

[LSB]

@tulongtou 谢谢 果然是 urllib3 版本问题
