根因分析

Selenium 无法找到 ChromeDriver 可执行文件。这发生在 ChromeDriver 未安装、不在 PATH 中，或版本与已安装的 Chrome 浏览器不匹配时。

English

Selenium cannot find the ChromeDriver executable. This occurs when ChromeDriver is not installed, not in PATH, or the version does not match the installed Chrome browser.

解决方案

  1. 95% 成功率 
    from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

  2. 92% 成功率 
    from selenium import webdriver

driver = webdriver.Chrome()  # Auto-downloads driver

无效尝试

常见但无效的做法:

  1. 80% 失败

    This makes tests non-portable and breaks on other machines or CI environments with different paths.

  2. 70% 失败

    This works locally but is not reproducible. The driver may be outdated or incompatible with the browser version.
