问题描述
代码如下：
from selenium import webdriver from selenium.webdriver.common.by import By def test01(): driver = webdriver.Chrome() driver.get("https://www.baidu.com/") driver.find_element(by=By.ID,value='kw').send_keys("你好") driver.find_element(by=By.ID,value='su').click() if __name__ =="__main__": test01()
报错：
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 119 Current browser version is 124.0.6367.202 with binary path C:Program FilesGoogleChromeApplicationchrome.exe
解决过程：
打开debug，查看详细错误信息
参考Selenium官网：Unable to Locate Driver Error，使用logging打印debug日志
代码如下：
import logging from selenium import webdriver from selenium.webdriver.common.by import By logging.basicConfig(level=logging.DEBUG) logger = logging.getLogger('selenium') logger.setLevel(logging.DEBUG) def test01(): driver = webdriver.Chrome() driver.get("https://www.baidu.com/") driver.find_element(by=By.ID,value='kw').send_keys("你好") driver.find_element(by=By.ID,value='su').click() if __name__ =="__main__": test01()
debug日志显示
从日志信息可以看出处理过程：
1、查找Selenium Manager执行文件并调用
2、通过Selenium Manager查找chromedriver 位置和版本
3、通过Selenium Manager查找browser位置和版本
4、判断browser和chromedriver版本是否兼容

删除现有的chromedriver.exe
删除现有的chromedriver.exe：H:studyseleniumdriverschromedriver.exe，让Selenium Manager自己请求合适的chromedriver.exe版本，重新执行程序，程序通过，查看debug日志，详细过程如下：
1、查找Selenium Manager执行文件并调用
2、通过Selenium Manager查找发现没有现成的chromedriver
3、通过Selenium Manager查找browser位置和版本
4、通过Selenium Manager请求兼容brower版本的chromedriver
