1、报错信息如下：
- [root@develop bin]# yum
- [root@develop local]# yum -y install prce
- 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:
- 2.6.1 (r261:67515, Aug 7 2010, 11:36:17)
- [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]
- If you cannot solve this problem yourself, please go to
- the yum faq at:
- http://wiki.linux.duke.edu/YumFaq
错误原因：错误信息描述为 yum 所依赖的python 不相符，请安装相对应的python即可
2、查看yum版本
[root@develop local]# rpm -qa |grep yum
yum-3.2.8-9.el5.centos.1
yum-metadata-parser-1.1.2-2.el5
3、查看python版本
- [root@develop local]# whereis python
- python: /usr/bin/python2.4 /usr/bin/python /usr/lib/python2.4 /usr/local/bin/python2.6 /usr/local/bin/python2.6-config /usr/local/bin/python /usr/local/lib/python2.6 /usr/share/man/man1/python.1.gz
果然装了两个版本python
4、执行python，查看到使用2.6.1的版本
- [root@develop local]# python
- Python 2.6.1 (r261:67515, Aug 7 2010, 11:36:17)
- [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
- Type "help", "copyright", "credits" or "license" for more information.
- >>>
5、猜测yum调用了高版本的python。
6、解决方法：
查找yum和 yum-updatest文件,并编辑此py文件
- [root@develop local]# which yum
- /usr/bin/yum
- [root@develop local]# vi /usr/bin/yum
- [root@develop local]# vi /usr/bin/yum-updatest
将
#!/usr/bin/python
改为:
#!/usr/bin/python2.4
