PyCharm抛出的错误（完整）：

Traceback (most recent call last):
  File "D:/PycharmProjects/untitled/test.py", line 11, in <module>
    driver = webdriver.Chrome(executable_path=driver_path)

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 77

主要是这句：

This version of ChromeDriver only supports Chrome version 77

看出来没，意思是版本不支持

解决方法（chrome为例）：

打开浏览器在地址栏输入：chrome://version/

得到浏览器的版本信息，如图例：

查看版本对应的驱动：

点这查看！！！

下载对应的驱动：

解压后到一个文件夹里，记住文件夹路径，使用时如下图：

from selenium import webdriver

driver_path = r"D:\Software_installation_program\chromedriver\chromedriver_win32\chromedriver.exe"
driver = webdriver.Chrome(executable_path=driver_path)

问题总结：

我最开始以为chromedriver.exe是通用的，版本越高越能适配，结果发现我想多了，凉凉~
