CentOS6.5配置python3.7安装后ssl问题

摘要：解决Python3安装中的SSL问题

报错明细

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

解决办法

由于系统是CentOS release 6.7，所有openssl的版本为 OpenSSL 1.0.1e ,而python3.7需要的openssl的版本为 1.0.2 或者 1.1.x,

  • 需要对openssl进行升级
  • 并重新编译python3.7.0 export LDFLAGS="-L/usr/local/openssl/lib/"
