想用yum 安装一个包，发现yum不能使用如下。
[root@done1 yum]# yum
There was a problem import[separator]ing one of the Python modules
required to run yum. The error leading to this problem was:
No module named rpm
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:
2.5.2 (r252:60911, Jul 2 2010, 11:08:48)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)]
If you cannot solve this problem yourself, please go to
the yum faq at:

从脚本里查看,加载了yum 和 yummain 模块错误
[root@done1 yum]# ls /usr/local/python2.5/lib/python2.5/site-packages/yum/
ls: /usr/local/python2.5/lib/python2.5/site-packages/yum/: No such file or directory
[root@done1 yum]# python -V
Python 2.5.2
ls: /usr/local/python2.5/lib/python2.5/site-packages/yum/: No such file or directory
[root@done1 yum]# python -V
Python 2.5.2
后来得知 redhat yum 必须在 python2.4下才能运行
[root@done1 yum]# ll /usr/bin/python
lrwxrwxrwx 1 root root 34 Jul 5 17:40 /usr/bin/python -> /usr/local/python2.5/bin/python2.5
[root@done1 yum]# rm -rf /usr/bin/python
[root@done1 yum]# ln -s /usr/bin/python2.4 /usr/bin/python
yum命令正常
