试过将chormedriver放到py安装目录 浏览器安装目录 项目目录下都没用
后来搜到一个解决方法 分享一下
报错原文

from selenium import webdriver
driver = webdriver.Chrome()
url = 'https://baidu.com'
driver.get(url)

报错selenium.common.exceptions.WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 1

在webdriver.Chrome()括号加入executable_path=‘chromedriver的地址’

from selenium import webdriver
driver = webdriver.Chrome(executable_path = 'D:\PY\chromedriver.exe')
url = 'https://baidu.com'
driver.get(url)

ok
