过去几天，我的代码中一直收到无法解析模块索引的消息，并找到了临时解决方案，但无法找到永久修复。
在过去的几天里，我一直收到此错误，并且当我运行“npm start -- --reset-cache”时找到了临时解决方案，但是每当我再次运行“react-native run-android”时，都会出现相同的错误弹出。这就是错误。
为什么会出现此错误？如何在不每次都使用临时解决方案的情况下解决该错误？

此问题是由于最新 React Native 版本中的错误引起的0.59: https://github.com/facebook/react-native/issues/24112 https://github.com/facebook/react-native/issues/24112
几个小时前发布了修复程序。请升级到react-native0.59.2.
