yum命令执行报错（python升级导致）
升级python版本后，yum无法使用。1、报错信息如下：
[*]# yum -y install prce
[*]There was a problem importing one of the Python modules
[*]required to run yum. The error leading to this problem was:
[*]
[*] No module named yum
[*]Please install a package which provides this module, or
[*]verify that the module is installed correctly.
[*]
[*]It's possible that the above module doesn't match the
[*]current version of Python, which is:
[*]2.6.1 (r261:67515, Aug 7 2010, 11:36:17)
[*]
[*]
[*]If you cannot solve this problem yourself, please go to
[*]the yum faq at:
[*]http://wiki.linux.duke.edu/YumFaq
错误原因：错误信息描述为 yum 所依赖的python 不相符，请安装相对应的python即可
2、执行yum查看信息
[*]# yum
[*]There was a problem importing one of the Python modules
[*]required to run yum. The error leading to this problem was:
[*]
[*] No module named yum
[*]
[*]Please install a package which provides this module, or
[*]verify that the module is installed correctly.
[*]
[*]It's possible that the above module doesn't match the
[*]current version of Python, which is:
[*]2.6.1 (r261:67515, Aug 7 2010, 11:36:17)
[*]
[*]
[*]If you cannot solve this problem yourself, please go to
[*]the yum faq at:
[*]http://wiki.linux.duke.edu/YumFaq
[*]提示当前版本是2.6.1可能版本不匹配。没有yum依赖的包。
3、查看yum版本
[*]# rpm -qa |grep yum
[*]yum-3.2.8-9.el5.centos.1
[*]yum-metadata-parser-1.1.2-2.el5
4、查看python版本
[*]# whereis python
[*]python: /usr/bin/python2.4 /usr/bin/python /usr/lib/python2.4 /usr/local/bin/python2.6 /usr/local/bin/python2.6-config /usr/local/bin/python /usr/local/lib/python2.6 /usr/share/man/man1/python.1.gz
果然装了两个版本python
5、执行python，查看到使用2.6.1的版本
[*]# python
[*]Python 2.6.1 (r261:67515, Aug 7 2010, 11:36:17)
[*] on linux2
[*]Type "help", "copyright", "credits" or "license" for more information.
[*]>>>
6、猜测yum调用了高版本的python。
7、解决方法：
查找yum文件,并编辑此py文件
[*]# which yum
[*]/usr/bin/yum
[*]# vi /usr/bin/yum
[*]将
[*]#!/usr/bin/python
[*]改为:
[*]#!/usr/bin/python2.4
[*]然后保存OK.
补充：yum基于python写的。
