pip install webdriver-manager
安装好后，将关于驱动的代码改为:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
他会将webdriver下载到缓存中：
====== WebDriver manager ======

driver = webdriver.Chrome(ChromeDriverManager().install())
