React-Native: Failed to load bundle. Cannot read property 'throwlfClosureRequired'
Change the version of "babel-preset-react-native" to "4.0.0". For the lastest version 5.0.0, the issue arises.
- Run npm install after the version change. Then start the emulator.
- Even then if you face issue, delete your node_modules directory, repeat step 1.
- Restart your machine if you see the issue again even after all tries.
Check github issue
I got the above mentioned error just now. I am using React Native v0.57 and my json file had this
{
"name": "AwesomeProject",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"react": "16.5.0",
"react-native": "0.57.1"
},
"devDependencies": {
"babel-jest": "23.6.0",
"jest": "23.6.0",
"metro-react-native-babel-preset": "0.45.6",
"react-test-renderer": "16.5.0"
},
"jest": {
"preset": "react-native"
}
}
I added "babel-preset-react-native": "4.0.0", and removed "metro-react-native-babel-preset": "0.45.6" in the "devDependencies" and the error was resolved.
