概述

因为非常复杂的原因导致系统无法使用yum命令，并提示如下错误。

[root@localhost ~]# yum list wget
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

No module named sqlitecachec


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:
2.6.6 (r266:84292, Feb 22 2013, 00:00:18)
\[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)\]

`If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq`
