Creator 2.4.0 使用Bundle后加载子包时Error: Cannot find module 'xxx'

Creator 2.x
#1

使用Creator 2.4.0构建iOS，原本没用Bundle时，一切正常。但因为index脚本大概有3-4M，所以拆了个子包出来，在主包加载完显示了加载场景后再加载子包里的脚本，代码如下：
cc.assetManager.loadBundle(“Sub”, (error, bundle) => {
// 这里还需要对bundle做什么处理吗？？
}

构建iOS项目后运行iOS项目，总是报：
ScriptEngine::evalString script assets/Sub/index.f8e00.js, failed!
ERROR: Error: Cannot find module ‘protobufjs’, location: assets/main/index.c5101.js:11:26

半路出家，求高人指点啊！！！！

补充：主包-Main，子包-Sub

在Sub子包加载后，通过require的方式，调用Sub里的某个脚本初始化逻辑。

我现在试了是要将jsb-link目录删除后，重新编译才行。
但现在cc.assetManager.loadBundle 加载远程目录，第一次可以，第二次重启后就加载失败，找不到文件了
