Unable to resolve module expo-constants from C:\Users\HP\Desktop\React Native\HelloApp\node_modules\expo-asset\build\LocalAssets.js: expo-constants could not be found within the project or in these directories:

>Solution :

Is it safe to assume you have run: expo install expo-constants?

If not, do that, and rebuild.

If this is not solving your error try:

• Deleting package-lock and node modules
• rerun npm install

If neither of the above solutions work, please provide more information.

Edit: Constants documentation.
