标签： javascript android reactjs react-native native

我在商店和应用程序的统计信息中最近有一个Android react原生应用程序，我可以看到一些JavaScript异常，并且我提供了一些错误代码。我已经阅读了一些内容，告诉我代码中的错误在哪里，或者当这个错误弹出给最终用户但是还没有找到解决方案时。我知道如何解决这个问题或者这个文本意味着什么？

1 个答案:

答案 0 :(得分：0)

没有代码，我几乎无法回答，但这是我的猜测：

错误表示变量未填充或尚未存在，而您的代码在某处要求它。 尝试找到'n._currentElement'和'e.getHostNode'，我建议使用Cmd / Ctrl + F.如果你能找到这些变量的使用位置，也许你也可以找出错误的产生位置。

祝你好运！
