项目需要升级，按照官方要求先升级到2.4.3再升级到3.2.0.
目前我们用2.4.3打开，运行没问题，构建的时候提示
Build Failed: Error: TypeError: this.objects.has is not a function
代码里面搜了this.objecets.has，发现没有相关代码。
有没有遇到同样问题的？
看错误堆栈
Build Failed: Error: TypeError: this.objects.has is not a function

不是很清楚，不过或许可以检查一下有没有循环引用
谢谢，我再查查看
我从2.3.2 到2.4.2，一个版本一个版本升上去都没问题，就是2.4.3有问题
