os version：

[root@lixora etc]# cat redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)


---运行yum 报错

[root@lixora ~]# yum install dialog

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:
2.7.8 (default, Jul 16 2014, 08:48:25) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-52)]


If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq
  


[root@lixora ~]# rpm -qa |grep yum
yum-security-1.1.16-21.el5
yum-updatesd-0.9-2.el5
yum-metadata-parser-1.1.2-3.el5

[root@lixora ~]# which yum 

/usr/bin/yum



[root@lixora ~]# vi /usr/bin/yum
