A Class already exists with the same

Creator 2.x
#1

Cocostor 版本：2.4.8（其实我们用的2.4.11也出现了）
在打包完成后，在对应平台（微信小游戏，抖音，App等）上运行是会出现以下错误：

JS: A Class already exists with the same classname : “SpineCom”.
JS: A Class already exists with the same cid : “d2162Vkv0lCQYV1sS1qbL1p”.
JS: A Class already exists with the same classname : “BossBase”.

只会打包后运行才会有这个错误。
不是每次都出现，偶尔出现（打几次包后，就会出现一次，可能会连续出现）。
一般情况在重新构建（或者删除temp，library后再构建），本次不会出现。
正常本地开发中没有出现过。

重复加载了.
以前做热更新时候,碰到过,改了一下底层的js.unregisterclass. 你搜一下.这个问题类似的.在js.register的时候,调用一下.

我感觉这样修改就可以了吧，每次都覆盖掉之前的。
var registered = table[id];
if (registered && registered !== constructor) {
if (CC_DEV || CC_EDITOR) {
cc.warn(‘A Class already exists with the same ’ + key + ’ : "’ + id + ‘". It will be overwritten.’);
}
table[id] = constructor;
}
