无法解析模块`./index` [英] Unable to resolve module `./index`

问题描述

过去几天我一直在我的代码中收到无法解析模块索引的问题，并且找到了一个临时解决方案，但无法找到永久修复.

I've been receiving an unable to resolve module index in my code the past few days and have found a temporarily solution but am unable to find a permanent fix.

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，弹出同样的错误.这是错误.

I've been receiving this error for the past few days and have found a temporary solution when I run "npm start -- --reset-cache", but whenever i run "react-native run-android" again, the same error pops up. This is the error.

为什么会出现这个错误，如何在不每次都使用临时解决方案的情况下解决它?

Why is this error appearing and how can I solve it without using my temporary solution each time?
