React-Native-Reanimated: error: node_modules\react-native-reanimated\src\index.ts:

Question

I was making new project and I can't run the android emulator with this error.

It is located at 'node_modules\react-native-reanimated\src\index.ts' and this is just the code there:

// tree-shaken side effects
import './reanimated2/js-reanimated/global';

// @ts-ignore backward compatibility with treeshaking
export * from './reanimated1';
export * from './reanimated2';
export * as default from './Animated';

Im not sure what to do, please help. Thank you in advance!

Answer 1

I also search for an answer and this worked for me.

Visit this expo reanimated docs link https://docs.expo.dev/versions/latest/sdk/reanimated/#installation

and I added this in my 'babel.config.js' file

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['module:metro-react-native-babel-preset'],
    plugins: ['react-native-reanimated/plugin'],
  };
};

I think the presets depends if you are using expo. Here is the original code given by the docs:

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
    plugins: ['react-native-reanimated/plugin'],
  };
};

you can see that I used my default preset which is module:metro.

I used the original code from the docs for babel.config.js and ran npx expo start --clear which cleared the bundler cache, and everything worked again. – Cynthia

Answer 2

I've been facing this problem for about 12 long hours, and the solution for this problem was simply to

1. Copy and paste this code below inside the babel.config.js file.

     return {
       presets: ["babel-preset-expo"],
       plugins: ["react-native-reanimated/plugin"],
     };
   };
   

2. Run your application using npx expo start -c

Answer 3

I ran this command expo start -c everything was working fine. After that, I've stopped the app with Ctrl+c and run a normal npm start and there were no problems with it since
