python脚本中selenium启动浏览器报错os.path.basename(self.path), self.start_error_message) selenium.common.excep      
                           
                   
                   
                                            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")
12345
报错提示如下所示：
Traceback (most recent call last):

    stdin=PIPE)

    startupinfo)

During handling of the above exception, another exception occurred:

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；
3.将Chrome替换掉原脚本中的Firefox，保存文件并运行。
# -*- coding:utf-8 -*-
from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://www.baidu.com")

driver.find_element_by_id("kw").send_keys("Selenium2")
driver.find_element_by_id("su").click
driver.quit()
