RN running project Error: Unable to resolve module

description¶

Today I encountered a problem with the debugging demo. I used the react-native run-ios command to start the app. When the bundle was loaded, the local package service reported the following error:

error¶

Error: Unable to resolve module ./debugger-ui/debuggerWorker.js from ``:

Corresponding problems were found in the issues on the React-Native official website, but from the feedback below, most of them are about the version of rn. The current version of my demo is also 0.62.2.

"react": "16.11.0",
 "react-native": "0.62.2",

solution¶

Open the React Native Debug Menu page, close and open debug again.
