yum安装错误！！！！！！！！！！111

jjx81622

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:

下载YUM源代码安装后，运行/usr/bin/yum update出现如上错误，

配置文件：/root/etc/yum/yum.conf

# in /etc/yum/repos.d
