Question

when I use yum in the shell,the error message is no module named yum, so I edit the /usr/bin/yum change the first line to another version of python, but nothing changes,and when I user different python to import yum, it brings out different error

and when i use yum ,the message is like this: the yum is ok before i use "rpm -e --nodeps pycurl" to remove pycurl...i need some help:(

Answer 1

Changing the first line of /usr/bin/yum to the default version of python may help.

eg.change #!/usr/bin/python to #!/usr/bin/python2.4
