it shows when I start expo project, so how can I fix this?

[Reanimated] Mismatch between JavaScript part and native part of Reanimated (3.0.2 vs. 2.14.4). Did you forget to re-build the app after upgrading react-native-reanimated? If you use Expo Go, you must downgrade to 2.14.4 which is bundled into Expo SDK.

ERROR TypeError: Cannot read property 'create' of undefined, js engine: hermes

ERROR Invariant Violation: "main" has not been registered. This can happen if:

* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.

* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called., js engine: hermes

This happens when there is a mismatch between version of reanimated . To Fix------- We have to make the version same ,so run npm i react-native-reanimated@version of native part,this will make your react-native-reanimated version same as one on your native device.

Note that if you are using expo you must install the exact version bundled with expo. The simplest way to do that is :

npx expo install react-native-reanimated

I've tried a lot too. This solution worked for me.

  1. Delete node_modules folder

  2. Run "npm install [email protected]"

  3. Dependency version not starting with tilde(~) or caret(^) see also

    "dependencies": { ... "react-native-reanimated": "3.3.0" ... }

  4. Run npm install

  5. Run npx expo start --reset-cache

I faced the same issue, resolved by adding resolution to package.json, which decides which version of the package should be used when this kind of conflicts occure.

  "resolutions": {
    "react-native-reanimated": "3.3.0"
  }

if u are using expo, there might be facing this kind of version issues due to differences between react native cli. The solution that u can try is to change your dependencies version of react native reanimated in package json to "react-native-reanimated": "^2.14.4", and run npm install. Last try to run command: expo start -c to reset the cache in your app and it will works perfectly fine!
