How to fix yum error: No module named CElementTree?

  • 772

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

  1. 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

    Solution

    Try to download and install python-elementtree manually:

    x86_64

    wget http://mirrors.usc.edu/pub/linux/distributions/centos/5.8/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm
sudo rpm -Uvh python-elementtree-*.rpm

    i386

    wget http://mirrors.usc.edu/pub/linux/distributions/centos/5.8/os/i386/CentOS/python-elementtree-1.2.6-5.i386.rpm
sudo rpm -Uvh python-elementtree-*.rpm

    Troubleshooting

    Error: 'package python-elementtree-1.2.6-7.el4.rf.i386 (which is newer than python-elementtree-1.2.6-5.i386) is already installed' or similar

    Try to replace the package, even it's installed by:

    sudo rpm -iv --replacepkgs python-elementtree-*.rpm

    or:

    sudo rpm -iv --replacefiles python-elementtree-*.rpm

    or finally:

    sudo rpm -iv --force python-elementtree-*.rpm
