参考技术A 直接使用编译好的包安装就行了

1安装selenium和浏览器驱动

1、安装selenium

　　1）win下win键 + r 打开运行界面，并输入CMD，点击确定

　　　　

 

 　　

　　2）输入   pip  install  selenium   按回车

　　　　

 

　　　　ps：我这边已经下载过了，就不重复下载了，如果没有报错，等待执行完毕即可

　　

　　3）验证是否安装成功

　　　　输入：pip  show selenium

　　　　

 

 　　　　显示以上信息则说明安装成功

 

3、浏览器驱动安装（谷歌浏览器）

　　1）查看浏览器版本（我的为83.0.4）

　　　　

 

 　　

　　2）打开页面：http://chromedriver.storage.googleapis.com/index.html   找到83对应等驱动，个人不建议下载最新版，可能会存在bug

 　　　　

 

 

　　3）点击对应的文件夹，下载对应的系统

　　　　

 

 　　4）下载之后解压，存放到python目录下，并双击一次即可
