首先得下载protobuf-gen-lua的插件，插件Git地址在此。

下载完之后进入到protoc-gen-lua\plugin这个目录，并在其中建立一个批处理文件：

@python E:\3rd\quick-x-protobuf\proto-gen-lua\protoc-gen-lua\plugin\protoc-gen-lua

然后进入到上一篇笔记中的addressbook.proto所在的文件夹内，运行如下命令：

protoc --lua_out=生成的lua存放地址 --plugin=protoc-gen-lua=上面新建的bat的完整地址 addressbook.proto

回车。

我们到目标地址下面就会看到一个addressbook_pb.lua文件，内容如下：
