linux操作系统安装python3

首先是下载python3,现在的最高版本是3.1.1
for linux。
我的放置路径是/home/python下放置Python-3.1.1.tgz,执行以下系列操作:
1.解压:tar zxvf Python-3.1.1.tgz----生成解压包Python-3.1.1
2.转换到Python-3.1.1路径下,执行./configure
3.make
4.make install
在rehl5中已经默认安装了python2.4,所以要做如下操作:
#cd /usr/bin
#ll |grep python   //查看该目录下python
#rm -rf python
#ln -s PREFIX/
Python-3.1.1/python ./python  //PREFIX为你解压python的目录
#python
检测改正之后的python版本
