Encountering the error message “Module AppRegistry is not a registered callable module” can be a frustrating experience when developing React Native applications, particularly when transitioning between different versions or platforms. This guide provides step-by-step solutions to help you resolve this issue effectively.
Common Causes and Solutions
1. Clean and Rebuild Your Project
One of the most straightforward solutions is to clean your project and rebuild it. This can often resolve issues related to outdated builds or corrupted caches.
- Navigate to your Android directory:
cd android - Run the Gradle clean command:
./gradlew clean - Return to your project root and execute:
react-native run-android
2. Verify Your Entry Files
Ensure that your index.android.js or index.js file is correctly set up to register the main component of your application. Your file should include:
import { AppRegistry } from "react-native";
import App from "./App";
import { name as appName } from "./app.json";
AppRegistry.registerComponent(appName, () => App);
3. Check for Unlinked Modules
If you’ve recently installed a plugin, ensure it is correctly linked:
react-native link4. Restart Node Processes
Sometimes, simply restarting the Node processes can resolve the issue. Use the following command to kill all Node processes:
killall -9 nodeAdvanced Troubleshooting
Reinstall Node Modules
If the issue persists, try reinstalling your node modules:
- Remove the node_modules directory:
rm -rf node_modules - Reinstall dependencies:
npm install - For iOS, run:
npx pod-install ios
