CentOS6编译安装Python3.7

准备编译环境

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel xz gcc-c++ gcc libffi-devel -y

下载并解压

wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
tar xf Python-3.7.3.tar.xz -C /usr/local/src/

编译安装

cd /usr/local/src/Python-3.7.3
./configure --prefix=/usr/local/python3 --with-ssl --enable-optimizations
make -j 4 && make install

最终提示如下，表示pip-9.0.1与setuptools-28.8.0同时安装成功
