Question

我有一个使用Expo构建的React Native项目，我们刚刚将其从SDK 35更新为SDK 36，但是现在它无法在Android和iOS上启动。在iOS上，它实际上会使Expo应用程序崩溃，而在Android上，它只是坐在白屏上。我假设这是其中一个依赖项的问题，但是我通常不是React Native开发人员，所以我不确定它可能是哪一个，但是可能基于以下异常而使用NetInfo？

以下是来自iOS模拟器的一些日志。

Answer 1

这是由于netinfo 4.x.x升级到netinfo 5.x.x（特别是5.9.7）中的问题而解决的。

升级到SDK 36后，Expo应用在启动时崩溃
