yum was working fine till I upgraded Python for the sake of django in my VPS.

It throws exactly this error:

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: 2.7.2 (default, Mar 7 2012, 08:41:42) [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)]

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

Why is this happening?

Does it mean I have to reinstall yum?

You should never upgrade the system Python, because there are other tools (like yum!) that depend on it. You should always install a newer Python alongside the system Python, and you should make sure that /usr/bin/python points to the system Python.

You should probably restore the original version of Python (you should be able to grab this from a CentOS mirror and install it using the rpm command), and then install a newer version of Python in an alternate location.

You may also need to re-install yum.

i did it !!! thanks – Thale Mar 7 '12 at 3:08
I used to alter python SRPM from Fedora for this sake, replacing all references to "python" with "python<version>" (it was python25 in my case) so there'd be no intersecting files/provisions/requirements. – ivan_pozdeev Mar 7 '12 at 7:50
