Centos6 Yum升级python2.6后 No module named cElementTree处理

概述

由于服务器Centos6系统版本过低导致网络上不存在历史rpm版本的安装包，通过卸载并安装最新版python2.6后导致yum仍然无法继续使用。

[root@localhost ~]# yum list wget
已加载插件：fastestmirror, product-id, subscription-manager
Updating Red Hat repositories.
Loading mirror speeds from cached hostfile
Traceback (most recent call last):
........
ImportError: No module named cElementTree

解决办法

通过查询相关文档发现缺少libexpat.so.1库依赖，但是版本包还存在，需要升级。

[root@localhost ~]# rpm -q expat
expat-2.0.1-9.1.el6.x86_64
[root@localhost ~]#  rpm -Uvh http://file.lolicp.com/Mirrors/Centos/6/Packages/expat-2.0.1-13.el6_8.x86_64.rpm
