파이썬은 protobuf를 사용합니다

#설치

tar zxvf protobuf-python-3.5.1.tar.gz
cd protobuf-3.5.1
./configure
make
make check
make install

#
protoc --version 확인

#python protobuf 모듈 설치
cd python
python setup.py install

 

#Write kms_sdk.proto 파일

# 생성 kms_sdk_pb2.py

protoc -I =. / --python_out =. / kms_sdk.proto
