LibreSSL is lacking host and IP verify parameters · Issue #381 · libressl-portable/portable https://github.com/libressl-portable/portable/issues/381

The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc atexit pwd
time

Failed to build these modules:
_ctypes

Following modules built successfully but were removed because they could not be imported:
_hashlib _ssl

Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381

更新编译安装 openssl版本
