Problem starting a react-native app in simulator - reactjs

Question

This is my package.json
{
"name": "Locals",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"#babel/runtime": "^7.3.1",
"react": "16.6.3",
"react-native": "0.58.3",
"react-native-elements": "^1.0.0",
"react-native-vector-icons": "^6.2.0"
},
"devDependencies": {
"babel-core": "^7.0.0-bridge.0",
"babel-jest": "24.0.0",
"jest": "24.0.0",
"metro-react-native-babel-preset": "0.51.1",
"react-test-renderer": "16.6.3"
},
"jest": {
"preset": "react-native"
}
}
And I get following logs of failure:
Loading dependency graph, done. error: bundling failed: Error: Cannot

Answer 1

Run rm -rf node_modules && npm install to reinstall the dependencies.
Make sure that react-native-vector-icons is properly linked. Usually you should have this line within android/app/build.gradle:
apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"
More info here:
https://github.com/oblador/react-native-vector-icons#android
Kill the npm server (ctrl+c or just run kill -15 [pid]) and restart it using npm start -- --reset-cache
Finally, don't forget to rebuild your app:
./android/gradlew clean && react-native run-android
