linux下原来安装的python是2.4,现在需升级至2.7.
1.首先下载2.7的压缩包:
wget http://www.python.org/ftp/python/2.7.1/Python-2.7.1.tgz
2.解压安装:
$ tar -xvf Python-2.7.1.tar
$ mv Python-2.7.1 /usr/local/
$ cd Python-2.7.1
$ ./configure
$ make
$ make install
3.更改软链接:
ln -s /usr/local/Python-2.7.1/python ./python
4.测试:
输入python,显示如下:
Python 2.7.1 (r271:86832, Feb 24 2011, 09:20:11)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
