此处已经可以正常使用python2.7了
但是因为yum是使用的2.4的版本来用的,专题系统,所以 还需要修改一下
[root@~]# 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:
2.7.2 (default, Jul 14 2011, 00:20:14)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)]

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


[root@wangyuelou Python-2.7.2]# vim /usr/bin/yum

#!/usr/bin/python #修改此处为2.4的位置
[root@~]# vim /usr/bin/yum

#!/usr/bin/python2.4
