selenium安装后，需要安装浏览器驱动

google的驱动：chromedriver.exe

驱动版本与chrome版本对应的目录：

http://npm.taobao.org/mirrors/chromedriver/2.32/notes.txt

 

驱动各版本的下载地址：http://npm.taobao.org/mirrors/chromedriver

from selenium import webdriver

bs=webdriver.Chrome('C:\Program Files (x86)\Google\Chrome\Application\chromedriver')

chrome的首字母要大写，chromedriver要放到chrome.exe的目录下，调用时要给出chromedriver的全目录包括文件名‘chromedriver.exe’

Firefox的驱动：从前的版本好像不需要安装驱动，后来需要安装firefoxdriver.exe,

Firefox Driver comes with Selenium/Webdriver itself. No need to launch an external server (like Chromedriver). It is all built-in. http://code.google.com/p/selenium/wiki/FirefoxDriver 再后来据说被GeckoDriver 替代了，没有核实，google用的比较顺手。

note: as of selenium 3.0, FirefoxDriver has been replaced by GeckoDriver (which is external)
