Cannot find module 'react-native-elements' - react-native

Question

Just created my first React-Native application and added my first library 'react-native-elements' using
yarn add react-native-elements
the package appears in my node_modules folder and yarn.lock, however I receive the following error:
Cannot find module 'react-native-elements'
app.tsx
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { Button, FormLabel, FormInput, FormValidationMessage } from 'react-native-elements';
export default function App() {
return (
<View style={styles.container}>
<FormLabel>Name</FormLabel>
<FormInput />
<FormValidationMessage>Error message</FormValidationMessage>
<Button>Send</Button>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});
