请教 selenium+Chrome 爬网页的问题

from selenium import webdriver 
from selenium.webdriver.remote.webelement import WebElement   

url="http://buy.ccb.com/searchproducts/pv_0_0_0_0_000.jhtml?query=*&selectCatId=12001001&catId=12001001&isBH=false&area=" 

driver =webdriver.PhantomJS(executable_path=r'D:\phantomjs\bin\phantomjs.exe')  #语句 1 

driver.get(url) 

pg=driver.find_element_by_xpath('//div[@class="main"]/div[@class="right"]/div[@class="page"]/a[@click][contains(text(),"下一页")]').click() 

上面的代码用于对 url 下方页码控件中的“下一页”按钮进行点击，以页码为 1 的网页为例，下一页按钮对应的元素是 <div class="main">下面的<div class="right">下面的<div class="page">下面的<a onclick="queryListByPage('2')">下一页</a>
代码使用 PhantomJS 浏览器可以正常运行。 
但是如果改用 Chrome 浏览器，即把语句 1 改写为 driver =webdriver.Chrome() 后就报出现如下错误： 

Traceback (most recent call last):
  File "d:\Python3\t1.py", line 37, in <module>
    pg=driver.find_element_by_xpath('//div[@class="main"]/div[@class="right"]/div[@class="page"]/a[@onclick][contains(text(),"下一页")]').click()

为何改用 Chrome 浏览器就会提示这个元素不可点击呢？请大家指点，谢谢！

driver.find_element_by_css_selector('body > div.main > div.right > div.page > a:nth-child(8)').click()

我试了这样的代码也不行
