TransformError when running React Native Getting Started project (iOS)

Question

I\'m having trouble getting the React Native Getting Started project to run.

I followed this guide: https://facebook.github.io/react-native/docs/getting-started.html<

Answer 1

It is caused by bug in babel-preset-react-native. Although solutions already provided here reinstall modules, package.json is still pointing to 3.0 of babel-preset-react-native and doesn't help you.

To solve this problem, I think you need to update package.json to point babel-preset-react-native to 2.1.

"dependencies": {
"react": "16.0.0-alpha.12",
"react-native": "0.47.1",
"babel-preset-react-native": "2.1.0"
},

See above, now babel-preset-react-native points to 2.1.0. Then,

rm -rf node_module
npm cache clean
npm i

And restart whichever android or ios. At least, this worked for me.
