$ protoc --go_out=./ hello.proto
protoc-gen-go: unable to determine Go import path for "hello.proto"
Please specify either:
• a "go_package" option in the .proto source file, or
• a "M" argument on the command line.
See https://developers.google.com/protocol-buffers/docs/reference/go-generated#package for more information.
--go_out: protoc-gen-go: Plugin failed with status code 1.
方法
syntax = "proto3";
option go_package="./;hello";
package hello;
message Hello {
string name = 1;
int32 age = 2;
string addr = 3;
}
添加
option go_package="./;hello";

option go_package = "path;name";
path 表示生成的go文件的存放地址，会自动生成目录的。
name 表示生成的go文件所属的包名
