ModuleNotFoundError: No module named 'pyexpat'
make: *** [install] Error 1

compile option is as follows:

CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-I$(brew --prefix openssl)/lib -I$(brew --prefix readline)/lib" pyenv install -v 3.6.2

set --with-system-expat option to configure:

PYTHON_CONFIGURE_OPTS="--with-system-expat" CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-I$(brew --prefix openssl)/lib -I$(brew --prefix readline)/lib" pyenv install -v 3.6.2

Oops! mistyped LDFLAGS...

PYTHON_CONFIGURE_OPTS="--with-system-expat" CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib" pyenv install 3.6.2

It just works!
