I follow the steps of react-native docs.
npx react-native init SelfApp --template react-native-template-typescript
and then follow the steps of react-native-navigation.
yarn add @react-navigation/native
yarn add react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view
then i add code
import 'react-native-gesture-handler';
to the first line of app.tsx.
then run yarn start, I got this error.
i tried a lot of times, but still in trouble, and here is my package.json
