react-native - 无法解析模块 `./index`

Question

过去几天，我在代码中收到了无法解析模块索引，并找到了临时解决方案，但无法找到永久修复。

过去几天我一直收到此错误，并且在我运行“npm start -- --reset-cache”时找到了一个临时解决方案，但是每当我再次运行“react-native run-android”时，同样的错误弹出。这是错误。

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它？

此问题是由最新的 React Native 版本中的错误引起的 0.59 : https://github.com/facebook/react-native/issues/24112
