我想使用需要Python一些较新的软件2.6,我们目前有两个2.4和2.6安装我们的专用服务器的CentOS,它看起来像这样的:
$ 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
如何将其切换2.6为默认开始使用python？
