I am using python2.7, I used to work on ubuntu and I never faced this kind of problem, but in CentOS I am getting this error, by the way I installed scrapy thats why you can see the first command working perfectly.

>>> import scrapy
>>> from scrapy.selector import HtmlXPathSelector

One more thing, what “from scrapy.selector import HtmlXPathSelector” has to do with math.py which is in the same folder

Well … This is not a problem with you, rather with CentOS vs. Ubuntu.

How did you install it? using pip or yum?

If you installed it from yum most likely the package is broken…
(just out of curiosity, it would be good to know where you downloaded the package from).
