python3,7 Can't connect to HTTPS URL because the SSL module is not available.

在Python3.7之后的版本，依赖的openssl，必须要是1.1或者以上版本，否则会出现Can't connect to HTTPS URL because the SSL module is not available错误。解决办法如下：

1.安装最新版的OpenSSL：

wget https://www.openssl.org/source/openssl-1.1.1d.tar.gz
tar -zxvf openssl-1.1.1d.tar.gz
cd openssl-1.1.1d
./config
make && make install

2.重新编译Python3.7.4：

./configure --with-openssl=/usr/local/ssl
make && make install

3.升级pip3：

pip3 install --upgrade pip
