centos7 安装python3

参考: https://blog.youkuaiyun.com/elija940818/article/details/79238813

环境依赖:

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-dev│-bash: pyhon3: command not foundel tk-devel gcc make

 

python3 安装依赖: libffi-devel  

wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libffi-devel-3.0.13-18.el7.x86_64.rpm
rpm -ivh libffi-devel-3.0.13-18.el7.x86_64.rpm

 

下载python源码:

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0a1.tar.xz 

tar -xvf Python-3.7.0a1.tar.xz

cd Python-3.7.0a1/

./configure prefix=/usr/local/python3

执行 make & make install

添加软连接:

ln -s /usr/local/python3/bin/python3 /usr/bin/python
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip

 

由于yum依赖python2.7 所以参照: https://www.cnblogs.com/JahanGu/p/7452527.html

修改yum 配置.

 

vi /usr/bin/yum

把#! /usr/bin/python修改为#! /usr/bin/python2
