Root Cause

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

generic

中文

Selenium 找不到 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 浏览器不兼容时。

Workarounds

  1. 98% success 
    pip install webdriver-manager
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())
  2. 90% success 
    driver = webdriver.Chrome(executable_path='/path/to/chromedriver')
  3. 95% success 
    Check Chrome version: chrome://version/
Download matching ChromeDriver from https://chromedriver.chromium.org/

Dead Ends

Common approaches that don't work:

  1. 70% fail

    If the version is incompatible with Chrome, Selenium will still fail with a different error.

  2. 80% fail

    This relies on PATH and may fail if chromedriver is not installed system-wide.

  3. 90% fail

    Does not solve the missing driver issue and may introduce other incompatibilities.
