centos 8 安装 python3.9

蓝色 是个人习惯

1、准备编译环境

dnf groupinstall 'development tools'

dnf install bzip2-devel expat-devel gdbm-devel ncurses-devel openssl-devel readline-devel sqlite-devel tk-devel xz-devel zlib-devel wget

dnf install libffi-devel -y

2、下载

mkdir download

cd download

wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0a6.tgz

3、编译&安装

tar -zxvf Python-3.9.0a6.tgz

cd Python-3.9.0a6

./configure --enable-optimizations

make && make altinstall

4、建立软连接

ln -s /usr/local/bin/python3.9 /usr/local/bin/python3

ln -s /usr/local/bin/pip3.9 /usr/local/bin/pip3
