在python脚本中，使用selenium启动浏览器报错，原因是未安装浏览器驱动，报错内容如下：
# -*- coding:utf-8 -*-
from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.baidu.com")
报错提示如下所示：

解决方案：安装Chrome浏览器驱动
1.下载 chromedriver_win32.zip，根据浏览器版本下载对应的压缩包；
下载地址：https://sites.google.com/a/chromium.org/chromedriver/downloads
2.解压后将chromedriver.exe文件放到系统环境变量Path路径下，例如：已将D:\Program Files\Python36\ 添加到系统环境变量Path路径下，将chromedriver.exe文件放到D:\Program Files\Python36\ 目录下即可；（20200319，把chromedriver.exe放到scripts提示错误）
