python3.8,.2 centos 安装

准备：

卸载 ： 

--python 卸载
where is python
rm -rf /usr/local/python3

 

1、 安装依赖

sudo yum install zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel libffi-devel

sudo yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel 

 预先安装以上包可以避免 在python使用 pip3过程中出现以下错误：【pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.】

 

2、下载 在python官网下载linux源码包

地址：https://www.python.org/ftp/python/3.8.3/Python-3.8.3rc1.tgz 

 

3、解压缩和安装python3.*

将安装包解压到 /tmp

tar xvf 解压缩 -C 指定目录

　　tar xvf Python-3.8.2.tgz -C /tmp/

解压后会生成 Python-3.8.2 目录，进入目录开始安装

       进入目录

　　cd /tmp/Python-3.8.1

       安装

　　./configure --prefix=/usr/local/python3

        make && make install
