CentOS 7下安装Python3.5
•安装python3.5可能使用的依赖
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel
•到python官网找到下载路径, 用wget下载
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz
•解压tgz包
tar -zxvf Python-3.5.1.tgz
•把python移到/usr/local下面
mv Python-3.5.1 /usr/local
•删除旧版本的python依赖
ll /usr/bin | grep python
rm -rf /usr/bin/python
•进入python目录
cd /usr/local/Python-3.5.1/
•配置
./configure
•编译 make
make
•编译，安装
make install
•删除旧的软链接，创建新的软链接到最新的python
rm -rf /usr/bin/python
ln -s /usr/local/bin/python3.5 /usr/bin/python
python -V
因此修改yum配置文件(sudo vi /usr/bin/yum)。 把文件头部的#!/usr/bin/python改成#!/usr/bin/python2.7保存退出即可
Enjoy your Python!
