下载相关浏览器chrome
(windows)https://www.chromedownloads.net/chrome64win/
windows会自己更新,需要自己去禁止更新,不然测着测着,浏览器升级了(除非你旧版本打开以后,就不要关闭),导致代码报错
(linux)https://www.chromedownloads.net/chrome64linux/
linux系统不会自动更新的,不要担心
下载相关浏览器chromedriver驱动
我这边下载的也是98.0.4758.102版本
https://registry.npmmirror.com/binary.html?path=chromedriver/98.0.4758.102/
