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、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
|
3、查看python版本

[root@develop

# whereis python
python:
/usr/bin/python2
.4
/usr/bin/python
/usr/lib/python2

/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
4、执行python，查看到使用2.6.1的版本
[plain]view plaincopyprint?
[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.
>>>
5、猜测yum调用了高版本的python。
6、解决方法：
查找yum和 yum-updatest文件,并编辑此py文件
|

[root@develop
local
]
# which yum
/usr/bin/yum
[root@develop
local
]
# vi /usr/bin/yum
[root@develop
local
]
# vi /usr/bin/yum-updatest
|
将
#!/usr/bin/python
改为:
#!/usr/bin/python2.4
然后保存OK.
如果不修改/usr/bin/yum ,则yum无法使用
如果不修改/usr/bin/yum-updatest 会出现如下错误
File "/usr/sbin/yum-updatesd", line 35, in
import dbus
ImportError: No module named dbus
当然，修改完后记着

[root@localhost google_appengine]
# /sbin/service yum-updatesd restart
Stopping yum-updatesd: [FAILED]
Starting yum-updatesd: [ OK ]

补充：yum基于python写的。
