Python3.10 在 centos7 上构建

概述

在 centos7 上安装 py3.10, 用到 openssl 库

env

• centos7.8
• Python-3.10.7.tgz

link

• https://www.jianshu.com/p/c3c8003d2760

01 下载 Python3.10.7

• https://www.python.org/ftp/python
• https://www.python.org/ftp/python/3.10.7/

02 requirement

yum install -y gcc gcc-c++ make autoconf

yum insall -y zlib-devel bzip2-devel ncurses-devel sqlite-devel readline-devel  libffi-devel


​

require openssl-1.1.1+, 需要自编译

03 install openssl

• https://www.openssl.org/source/
• https://www.openssl.org/source/openssl-1.1.1s.tar.gz

./config -fPIC --prefix=/usr/local/openssl
make -s -j4
make -s install -j4

注释：
--prefix：指定安装目录
-fPIC:编译openssl的静态库

Failed to build these modules:
_hashlib              _ssl                                   

Could not build the ssl module!
Python requires a OpenSSL 1.1.1 or newer

//编译构建
