1. 安装依赖环境
# 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
2. 下载Python3.7的安装包
# wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
3. 创建Python3的目录
# mkdir /usr/local/python3
4. 解压下载文件并切换目录
# tar -zxvf Python-3.7.0.tgz
# cd Python-3.7.0
5. 执行
# ./configure
运行后会提醒
If you want a release build with all stable optimizations active (PGO, etc),
please run ./configure --enable-optimizations
可以运行 ./configure --enable-optimizations 进行配置优化
# make && make install
6. 创建Python3的软链接
# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
7. 创建Pip3的软链接
# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
8. 测试命令 python3 和 pip3
# python3 -V
# pip3 -V
