Hi xenovia12​,

The error you’re seeing means that @builder.io/sdk-react-native@4.2.2 expects react@^18, but your project is using React 19.0.0.

Solutions

Option 1: Downgrade React to v18

If you don’t need React 19, the safest fix is:

npm install react@18 react-dom@18

This will satisfy @builder.io/sdk-react-native.

Option 2: Use --legacy-peer-deps (Not recommended for production)

This tells npm to ignore peer dependency conflicts, but it can lead to runtime bugs:

npm install --legacy-peer-deps

Use this only if you’re aware of compatibility risks.

Thanks,
