我正在使用python2.7，我曾经在ubuntu上工作，我从来没有遇到过这种问题，但是在CentOS中我得到了这个错误，顺便说一句，我安装了scrapy，这就是为什么你可以看到第一个命令完美运行

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

还有一件事，“来自scrapy.selector import HtmlXPathSelector”与math.py有什么关系，它位于同一个文件夹中

嗯......这不是你的问题，而是CentOS与Ubuntu。

你是如何安装它的？使用pip或yum？

如果您从yum安装了它，那么包裹很可能已损坏...... （出于好奇，最好知道你从哪里下载了包。）
