Mac python3 报错 cannot import name 'ssl'

重装python，有些失败经验，成功的写在最后

安装好brew后
brew install openssl
打开Python3.6.8源码包里的Modules/Setup.dist文件
打开这五行的注释

_socket socketmodule.c

SSL=/usr/local/ssl
_ssl _ssl.c \
         -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
         -L$(SSL)/lib -lssl -lcrypto

然后

export LDFLAGS="-L\$(brew --prefix  openssl)/lib"  
export CFLAGS="-I$(brew --prefix openssl)/include"
./configure --prefix=/your_install_path --enable-optimizations
make
make install

其中--enable-optimizations必须

以上均失败了，用stackoverflow.com/questions/23548188/how-do-i-compile-python-3-4-with-custom-openssl

以上均失败了，用stackoverflow.com/questions/46457404/how-can-i-compile-python-3-6-2-on-macos-with-openssl-from-homebrew

以上均失败了，最终成功版：

brew --prefix openssl

显示/usr/local/opt/openssl
Recompile Python and explicitly tell it where to find openssl with CPPFLAGS and LDFLAGS.

./configure CPPFLAGS="-I/usr/local/opt/openssl/include/openssl" LDFLAGS="-L/usr/local/opt/openssl/lib" --prefix=/your_install_path
make
make install
