Python scrapy中的奇怪错误（CENTOS 6.2）

还有一件事，“从scrapy.selector导入HtmlXPathSelector”与同一文件夹中的math.py有什么关系。。。这不是你的问题，而是CentOS和Ubuntu的问题

你是怎么安装的？使用

pip

或

yum

如果您是从

yum安装的，则该软件包很可能已损坏。。。
（出于好奇，很高兴知道您从哪里下载了该软件包）。
感谢OZ123，f您的快速回复，我安装了这么多版本的python，因为我的愚蠢，现在我正在手动删除所有内容并恢复python，在您执行导入scrapy后，请在它工作后通知您
目录（scrapy.selector）
的结果是什么？
