"no module named yum" problem

ufmale · 12-19-2007, 04:12 PM

I don't find any good explanation of how to fix the
"No module named yum"

I am using Redhat Enterprise 4 and just install a bunch of redhat packages recommened by http://www.eth0.us/yum-rhel
python came with Redhat install is 2.3
Found some instruction on the web to import yum in the python command line, it seems to work.

yum was intalled using src.tar from the duke website. Neither yum 2.6 nor 2.4 work for me. It still show the same message "No module named yum"

This is how i install yum

Code:

$ make
       // does not look like it do anything
      $ make install
      // looks like to copy a bunch of files

Can anyone help?

To save the problem (there is an error in the spec file) all you need to have or create is the /etc/yum.repos.d directory.

If needed as root type: mkdir /etc/yum.repos.d

Then copy this file named CentOS-Base.repo into the directory;

Code:

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#

Then to install from the CentOS repositories type something like;

yum install foo --enablerepo=c4*

A quick test: yum check-update --enablerepo=c4*

Followed your instruction, but still cannot get it to work. Do you see any obvious problem from the following error?

# mkdir /etc/yum.repos.d
# cd yum.repos.d
[root@a1 yum.repos.d]# vi CentOS-Base.repo
[root@a1 yum.repos.d]# cd
[root@a1 ~]# yum check-update --enablerepo=c4

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:
2.3.4 (#1, Feb 2 2005, 11:44:49)
[GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)]

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

There is a difference between c4 and c4*. Not sure if that is the only problem.

ufmale · 01-02-2008, 05:45 PM

tried both with and without *, and get the same error.

lazlow · 01-02-2008, 07:53 PM

Have you rebuilt the rpm per the instructions?

ufmale · 01-03-2008, 10:38 AM

i built from the src. Not sure how to build the rpm.src.
Remembered trying for other app, but does not seem to do anything..
is it just
$ rpmbuild yum.src.rpm?
do we need any install after that?
I am a newbie in Linux

lazlow · 01-03-2008, 03:54 PM

Just follow ALL the instructions in the link in post #2.
