**代码分析：** ```python 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() ``` **错误日志：** ``` selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 119Current browser version is 124.0.6367.202 with binary path C:\\Program Files\\Google\\Chrome\\Application\\chrome.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： ``` DEBUG:selenium.webdriver.common.selenium_manager:Selenium Manager binary found at: H:\\codes\\python\\automation\\SeleniumAuto\\.venv\\Lib\\site-packages\\selenium\\webdriver\\common\\windows\\selenium-manager.exe DEBUG:selenium.webdriver.common.selenium_manager:Executing process: H:\\codes\\python\\automation\\SeleniumAuto\\.venv\\Lib\\site-packages\\selenium\\webdriver\\common\\windows\\selenium-manager.exe --browser chrome --debug --language-binding python --output jsonDEBUG:selenium.webdriver.common.selenium_manager:chromedriver not found in PATH ``` **解决方法：** 根据错误日志中，chromedriver 版本不兼容当前浏览器版本（124.0.6367.202）。因此，需要删除现有的 ChromeDriver 檔案（`chromedriver.exe`）并重新下载 compatible 版本的 ChromeDriver。 **注意：** * 该代码需要安装 `selenium` 库才能运行。 * 请确保 ChromeDriver 运行在与浏览器相同的操作系统上。 * 下载 ChromeDriver 檔案时，请注意安全性和版本兼容性。

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 Files\Google\Chrome\Application\chrome.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:\study\selenium\drivers\chromedriver.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
