1、报错信息如下：

[root@develop local]# 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)

[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]

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

[root@develop bin]# 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)

[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]

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

[root@develop local]# 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

[root@develop local]# 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

[root@develop local]# python

Python 2.6.1 (r261:67515, Aug 7 2010, 11:36:17)

[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] 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

[root@develop local]# which yum

/usr/bin/yum

[root@develop local]# 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。
