根因分析

ChromeDriver 二进制版本与已安装的 Chrome 浏览器版本不匹配。Selenium 4.x 通过 Selenium Manager 自动管理驱动，但 PATH 上过时的 chromedriver 会优先使用并导致不匹配。

English

ChromeDriver binary version does not match the installed Chrome browser version. Selenium 4.x auto-manages drivers via Selenium Manager, but a stale chromedriver on PATH takes precedence and causes the mismatch.

解决方案

  1. 95% 成功率 
    which chromedriver && sudo rm $(which chromedriver)
pytest tests/e2e/ -v
# Selenium Manager downloads the correct driver on first run
  2. 90% 成功率 
    # Dockerfile
RUN apt-get install -y google-chrome-stable=124.* 
# or use selenium/standalone-chrome:124.0 image
# pytest with RemoteWebDriver pointing to the container

无效尝试

常见但无效的做法:

  1. 85% 失败

    Security risk and often blocked by corporate IT; also brittle since Chrome auto-updates.

  2. 90% 失败

    Headless still launches a real Chrome binary; the version check happens before mode selection.
