解决pip is configured with locations that require TLS/SSL, however the ssl module in Python is not ...

一、下载 openssl 编译安装

openssl 官方下载地址：https://www.openssl.org/source/

wget https://github.com/openssl/openssl/archive/OpenSSL_1_1_1d.tar.gz

解压

tar -zxvf OpenSSL_1_1_1d.tar.gz

二、编译安装

进入openssl-OpenSSL_1_1_1d

cd  openssl-OpenSSL_1_1_1d

指定安装路径并编译

./config --prefix=/usr/local/openssl // 指定安装路径
make && make install

三、替换当前系统的旧版本 openssl 「先保存原来的」

mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/lib64/openssl /usr/lib64/openssl.old
mv /usr/lib64/libssl.so /usr/lib64/libssl.so.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/lib/libssl.so /usr/lib64/libssl.so
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
ldconfig -v // 建立动态链接

四、最后查看当前系统 openssl 版本

openssl version

五、重新编译Python3.7

进入解压后的Python目录

cd Python-3.7.1
./configure --prefix=/usr/local/python3 --with-openssl=/usr/local/openssl
make
make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
