来自go-kit source :

Using gRPC and go-kit together is very simple.

First, define your service using protobuf3. This is explained in gRPC documentation. See add.proto for an example. Make sure the proto definition matches your service's go-kit (interface) definition.

Next, get the protoc compiler.

You can download pre-compiled binaries from the protobuf release page. You will unzip a folder called protoc3 with a subdirectory bin containing an executable. Move that executable somewhere in your $PATH and you're good to go!

所以只要确保 protoc 在你的 PATH 环境变量中。
