centos原系统安装了Python3.7.9兼用在安装一个python3.8

系统有个3.7.9版本的python 但是会遇到错误

usr/local/python3/lib/python3.7/site-packages/urllib3/connectionpool.py:1050: InsecureRequestWarning: Unverified HTTPS request is being made to host ‘www.xxx.com’. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#ssl-warnings

需要安装高版本的 这个版本有问题 我安装3.8版本的

安装编译依赖

sudo yum groupinstall "Development Tools"
sudo yum install zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel

下载Python 3.8源代码

wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz

解压并进入目录

tar -xf Python-3.8.0.tgz
cd Python-3.8.0

配置并编译

./configure --enable-optimizations
make -j `nproc`

安装

sudo make altinstall

验证安装

python3.8 --versionpip3.8  -V

这样就OK啦
