将默认的Python版本从2.4更改为2.6 [英] Change default Python version from 2.4 to 2.6

问题描述

我想使用一些需要Python 2.6的较新软件，并且我们目前在专用CentOS服务器上同时安装了2.4和2.6，如下所示:

I'm wanting to use some newer software that requires Python 2.6, and we currently have both 2.4 and 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

如何切换为开始使用2.6作为默认python?

How can I switch it to start using 2.6 as the default python?

推荐答案

以root用户身份

ln -sf /usr/bin/python2.6 /usr/local/bin/python

这将从/usr/local/bin/python->/usr/bin/python2.6建立符号链接 (替换旧的硬链接).

This will make a symbolic link from /usr/local/bin/python --> /usr/bin/python2.6 (replacing the old hardlink).
