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: 2.5.4 (r254:67916, Feb 24 2010, 10:03:49) [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
解决方法:
[root@vm10-254-206-95 ~]# which yum
/usr/bin/yum
[root@vm10-254-206-95 ~]# vi /usr/bin/yum
将
#!/usr/bin/python
改为:
#!/usr/bin/python2.6
然后保存OK.
