Centos – How to fix yum error: No module named CElementTree

centospythonyum

I've the following problem with yum:

$ 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 cElementTree

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:
2.4.3 (#1, Feb 22 2012, 16:06:13) 
[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:

My OS: CentOS release 5.8 (Final)

When trying to install python-elementtree manually from RPM package, it gives the following error:

$ sudo rpm -i http://mirror.centos.org/centos-5/5/os/i386/CentOS/python-elementtree-1.2.6-5.i386.rpm
package python-elementtree-1.2.6-7.el4.rf.i386 (which is newer than python-elementtree-1.2.6-5.i386) is already installed
$ sudo rpm -i http://mirror.centos.org/centos-5/5/os/i386/CentOS/python-elementtree-1.2.6-5.i386.rpm

Hmm, is python-elementtree still installed? The cEleementTree module should live in /usr/lib64/python2.4/site-packages/cElementTree.so (/usr/lib/... on 32bit systems). Does that file still exist?

If the package is missing, you can resintall it with rpm:

x86_64:

rpm -i http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm

i386:

rpm -i http://mirror.centos.org/centos-5/5/os/i386/CentOS/python-elementtree-1.2.6-5.i386.rpm
