No module named yum

yum 업데이트 했을 때 아래와 같은 에러가 보인다면 

#yum update

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 (r27:82500, Aug 24 2012, 08:08:08)

[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:

다시 설치한다.
