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，现在输入一下yum就会报错

01	[iyunv@local_redhat ~]# yum

02	There was a problem importing one of the Python modules

03	required to run yum. The error leading to this problem was:

04

05	No module named yum

06

07	Please install a package which provides this module, or

08	verify that the module is installed correctly.

09

10	It's possible that the above module doesn't match the

11	current version of Python, which is:

12	2.7.2 (default, Jul 14 2011, 00:20:14)

13	[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)]

14

15	If you cannot solve this problem yourself, please go to

16	the yum faq at:

17	http://wiki.linux.duke.edu/YumFaq

所以还需要修改一下

01	[iyunv@local_redhat Python-2.7.2]# vim /usr/bin/yum

02

03	#!/usr/bin/python #修改此处为2.4的位置

04	[iyunv@local_redhat ~]# vim /usr/bin/yum

05

06	#!/usr/bin/python2.4

07	[iyunv@local_redhat ~]# yum

08	Loaded plugins: fastestmirror

09	You need to give some command

10	usage: yum [options] COMMAND

11

12	List of Commands:

13

14	check-update Check for available package updates

15	clean Remove cached data

16	deplist List a package's dependencies

17	downgrade downgrade a package
