自己编译安装的Python3.10 pip装包提示 Can’t connect to HTTPS URL because the SSL module is not available.

背景

尝试在centos7上自己编译安装 Python3.10

yum update -y
yum groupinstall "Development Tools" -y 
yum install openssl-devel libffi-devel libffi-devel bzip2-devel -y
gcc --version

yum install wget -y

wget https://www.python.org/ftp/python/3.10.0/Python-3.10.0.tgz
tar xvf Python-3.10.0.tgz
cd Python-3.10.0
./configure --enable-optimizations 
make altinstall

python3.10 --version

在尝试安装pip包的时候提示我：“Can’t connect to HTTPS URL because the SSL module is not available.”

好像是编译安装的Python没有ssl模块

解决问题

单独编译安装openssl

wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz
tar zxvf openssl-1.1.1g.tar.gz
cd openssl-1.1.1g
./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl no-ssl2

make
make install

重新编译安装Python

cd Python-3.10.0
./configure --enable-optimizations --with-openssl=/usr/local/openssl
make altinstall

python3 -m ssl
