Answer 1

You seem to have no Metro-config module installed. Install this module.

npm i metro-config --save-dev

Answer 2

Add metro.config.js to your root project folder and add the following:

const {getDefaultConfig, mergeConfig} = require('@react-native/metro-config');
const config = {};
module.exports = mergeConfig(getDefaultConfig(__dirname), config);
