试图为谷歌学者应用程序运行python脚本

Question

我需要获取以下信息：

To Make a Google Scholar profile to estimate the number of 
citations per year from the graph plotted as part of the profile

来自以下脚本：

http://infohost.nmt.edu/~borchers/scrapescholarcitecounts.py

运行我得到的脚本：

Traceback (most recent call last):
  File "scrapescholarcitecounts.py", line 56, in <module>
    chart=m.group(1)
AttributeError: 'NoneType' object has no attribute 'group'

脚本是否过时了？我做错了什么？
