CentOS 5.9 comes with Python 2.4.3 installed. I installed a different Python version (2.7) and all hell broke loose. Yum stopped working with errors like a particular Python module was missing.
I searched for fixing this problem on various forums and found no useful help. Finally, I could fix it with following actions:
Delete conflicting Python
- Search other Python distributions on your machine. Run $whereis python and delete all directories that point to any Python version but 2.4.
- Delete contents of /usr/lib/python2.4/site-packages/yum/ by running $rm -rf /usr/lib/python2.4/site-packages/yum/*
- Delete contents of /usr/lib/python2.4/site-packages/rpmUtils/*
- You will start seeing errors as No module named yum now.
Install YUM
- Figure out what yum version does your machine expects. $rpm -q yum.
- On my machine, output was: yum-3.2.22-40.el5.centos
- Get the package: $wget http://yum.baseurl.org/download/3.2/yum-3.2.22.tar.gz
- Unzip and build it.
- $make
- You might see following error:
for d in rpmUtils yum etc docs po; do make PYTHON=python -C $d; [ $? = 0 ] || exit 1 ; done intltool-update –gettext-package=yum –pot make[1]: intltool-update: Command not found make[1]: *** [yum.pot] Error 127 make[1]: Leaving directory `/root/work/packages/yum-3.2.22/po’ make: *** [subdirs] Error 1
- You might see following error:
- I fixed the above error by changing the yum-3.2.22/Makefile and removing dependency “po” in the first line. It is harmless. If you start installing the intltool rpm, it ends up in many dependencies. It looked futile to me.
- Try make again. It will work now.
- Now, do make install
- This will copy yum related modules in your Python site-packages.
Install YUM dependencies
- Now, visit this link
- Look at CentOS 5.9 section and copy all lines for RPM installation in a file.
- Add –force to each rpm installation request as follows:
$~/work/packages/yum-3.2.22# rpm -Uvh –force http://mirror.centos.org/centos-5/5.9/os/x86_64/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm
- yum should work now
Hi,
great blog, but I am not able to run the commands in the following link
http://openvz.org/Install_yum
I get this error

Retrieving http://mirror.centos.org/centos/5.7/os/x86_64/CentOS/gmp-4.1.4-10.el5.x86_64.rpm

Can you please help me?
