When using pip3 install mysql-connector, it shows that protobuf is missing.
Then after searching, download protobuf-2.5.0.zip and protoc-2.5.0-win32 from google .zip,

The steps are as follows:
Put the protoc.exe in protoc-2.5.0-win32.zip under protobuf-2.5.0src and switch to protobuf-2.5.0Python
Execute the command python setup.py build ,

             python setup.py test, 
             python setup.py install

When executing python setup.py test, an error occurs, showing: can' not find google/protobuf/internal/test_bad_identifiers.proto
