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# yum
02There was a problem importing one of the Python modules
03required to run yum. The error leading to this problem was:
04
05No module named yum
06
07Please install a package which provides this module, or
08verify that the module is installed correctly.
09
10It's possible that the above module doesn't match the
11current version of Python, which is:
122.7.2 (default, Jul 14 2011, 00:20:14)
13
14
15If you cannot solve this problem yourself, please go to
16the yum faq at:
17http://wiki.linux.duke.edu/YumFaq
所以还需要修改一下01# vim /usr/bin/yum
02
03#!/usr/bin/python #修改此处为2.4的位置
04# vim /usr/bin/yum
05
06#!/usr/bin/python2.4
07# yum
08Loaded plugins: fastestmirror
09You need to give some command
10usage: yum COMMAND
