yum中的python版本错误
http://blog.sina.com.cn/s/blog_62c8f3c901012s5c.html
为了安装rrdtool,发现不是少这个就是少那个,最后发现yum也不能用。
从网上找的解决yum问题。

1、报错信息如下:
[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、执行yum查看信息
[root@develop bin]# yum
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)

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

提示当前版本是2.6.1可能版本不匹配。没有yum依赖的包。
3、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
4、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
5、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.
>>>
6、猜测yum调用了高版本的python。
7、解决方法:
查找yum文件,并编辑此py文件
[root@develop local]# which yum
/usr/bin/yum
[root@develop local]# vi /usr/bin/yum


#!/usr/bin/python
改为:
#!/usr/bin/python2.4

然后保存OK.

补充:yum基于python写的。
