1、CentOS7
# 准备编译环境 sudo yum groupinstall -y 'Development Tools' sudo yum install -y kernel-headers zlib-devel bzip2-devel openssl-devel ncurses-devel libffi-devel xz-devel sqlite-devel sqlite*
# 下载Python3.8.8压缩包 wget --no-check-certificate https://www.python.org/ftp/python/3.8.8/Python-3.8.8.tgz
# 创建安装目录 mkdir /usr/local/python38
# 解压 tar -zxvf Python-3.8.8.tgz
# 切换到解压后的根目录 cd Python-3.8.8/
# 编译安装 ./configure --with-ssl --prefix=/usr/local/python38 make make install
|
Linux里原来的python命令还是指向Python2,这里创建python3的软链接指向Python3,这样Python2和Python3就都可以用了。
# -snf 强制替换已有的链接 ln -snf /usr/local/python38/bin/python3 /usr/bin/python3
|
保留pip指向Pip2,创建pip3的软链接指向Pip3。
# -snf 强制替换已有的链接 ln -snf /usr/local/python38/bin/pip3 /usr/bin/pip3

2、Ubuntu16.04
# 添加源仓库 sudo add-apt-repository ppa:jonathonf/python-3.8
# 先更新,再安装 sudo apt-get update sudo apt-get install python3.8
# 安装pip sudo apt-get install python-pip sudo apt-get install python3-pip
# 升级pip pip install --upgrade pip
