问安装mysqldb时没有名为Yum的模块

EN

root@osp [/home/hmm/RentalWanted]# 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:
2.7.3 (default, Dec 11 2012, 20:12:43) 
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
