问题

$ 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.

解决

#添加
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
