我引入的是protobuf库，在其他平台都正常，在百度小游戏require报错，返回null,添加日志百度小游戏走的amd规范，其他走的是commonjs
(function(global, factory) {
/* AMD */ if (typeof define === 'function' && define["amd"])
define(["bytebuffer"], factory);
/* CommonJS */ else if (typeof require === "function" && typeof module === "object" && module && module["exports"])
module["exports"] = factory(require("bytebuffer"), true);
/* Global */ else
(global["dcodeIO"] = global["dcodeIO"] || {})["ProtoBuf"] = factory(global["dcodeIO"]["ByteBuffer"]);
})(this, function(ByteBuffer, isCommonJS) {
}
