1、下载python39

bash 复制代码

https://mirrors.huaweicloud.com/python/3.9.0/Python-3.9.0.tgz

2、拷贝到Linux环境（当然也可以直接在Linux环境使用wget直接下载）

先安装一下依赖，不然编译会有问题

bash 复制代码

sudo yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

3、安装

bash 复制代码

tar -zxvf Python-3.9.0.tgz

配置安装路径

bash 复制代码

cd Python-3.9.0/
 
./configure prefix=/usr/local/python39

编译并安装

bash 复制代码

make && make install

添加软链接

bash 复制代码

ln -sf /usr/local/python39/bin/python3 /usr/bin/python3
 
ln -sf /usr/local/python39/bin/pip3 /usr/bin/pip3

验证

bash 复制代码

python3 --version
