1._ctypes 模块构建失败
build correctly but finished with this message:
Failed to build these modules:
_ctypes
解决
Are you using Ubuntu or other Linux distribution? This problem is because you didn’t install the dependency package.
You may first try to use the instruction at devguide:
http://cpython-devguide.readthedocs.io/setup.html#build-dependencies
Or, assume you have install build-essential and python3-dev …etc., maybe you lost to install libffi-dev, just simply apt-get install libffi-dev and rebuild to solve this problem.
ssl模块构建失败
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,

解决
输入命令 openssl version 查看当前安装的openssl版本：
codedancing@Ubuntu:/usr/local/src/Python-3.7.6$ openssl version
OpenSSL 1.1.1d 10 Sep 2019
即使OpenSSL是最新版本，仍然需要重新安装OpenSSL：
（1）访问 OpenSSL官网 下载最新的 openssl 安装包
（2）解压安装包： sudo tar -zxf openssl-1.1.1d.tar.gz
（3）进入安装包依次执行：./config 、 make、 make test、 make install
