I'm wanting to use some newer software that requires Python
2.6, and we currently have both
2.6 installed on our dedicated CentOS server, which looks like this:
$ which python /usr/local/bin/python $ which python2.6 /usr/bin/python2.6 $ which python2.4 /usr/local/bin/python2.4 $ ls -l /usr/local/bin/py* -rwxr-xr-x 1 root root 81 Aug 9 2007 /usr/local/bin/pydoc -rwxr-xr-x 2 root root 3394082 Aug 9 2007 /usr/local/bin/python -rwxr-xr-x 2 root root 3394082 Aug 9 2007 /usr/local/bin/python2.4
How can I switch it to start using
2.6 as the default
ln -sf /usr/bin/python2.6 /usr/local/bin/python
This will make a symbolic link from /usr/local/bin/python --> /usr/bin/python2.6 (replacing the old hardlink).
As an alternative, you can also just add an alias for the command "python" in the your bash shell's startup file.
so open the startup file: emacs ~/.bashrc
in the editor u append: alias "python" "python2.6"
and restart the shell.
