总结报错解决
问题一：安装时报错ModuleNotFoundError: No module named '_ctypes'的解决办法
1、执行如下命令：
yum install libffi-devel -y
2、从"./configure ..."重新安装Python3.7
问题二：pip3 install时报错“pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.”
先安装openssl-dev，然后重新编译安装，只是在编译的过程中加入 --enable-optimizations
ubuntu：
sudo apt-get install libffi-dev或者
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus
sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev
sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev
