根因分析

已安装的 ChromeDriver 版本与本地 Chrome 浏览器不匹配。常见于 Chrome 自动更新但 driver 未同步更新。

English

The installed ChromeDriver version doesn't match the local Chrome browser. This commonly happens after an automatic Chrome update without a corresponding driver update.

解决方案

  1. 94% 成功率 
    from selenium import webdriver

# Selenium Manager handles driver download automatically
driver = webdriver.Chrome()  # no Service path needed
  2. 90% 成功率 
    from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))

无效尝试

常见但无效的做法:

  1. 70% 失败

    Works until Chrome auto-updates again; brittle and requires manual re-pinning per machine.

  2. 80% 失败

    Headless mode doesn't bypass the version check; the SessionNotCreatedException is raised before browser launch.
