Error: Failed to initialize react-native-reanimated library

Question

I was working on a project on react native trying to create drawer navigation

• I installed a navigation drawer, gesture handler, and reanimated libraries

• and when I run I got an error 1st error :

  ERROR Error: Failed to initialize react-native-reanimated library, make sure you followed installation steps here: https://docs.swmansion.com/react-native-reanimated/docs/fundamentals/installation/

  1. Make sure reanimated's babel plugin is installed in your babel.config.js (you should have 'react-native-reanimated/plugin' listed there - also see the above link for details)
  2. Make sure you reset build cache after updating the config, run: yarn start --reset-cache, js engine: hermes

so I did according to the suggestion in this error I added plugins:['react-native-reanimated/plugin' in the babel.config.js and started with npm start ----reset cache that gave me another error:

2nd error

error: index.js: Unknown option: .Plugins. Check out https://babeljs.io/docs/en/babel-core/#options for more information about options.

here is my package.json

import {name as appName} from './app.json';

AppRegistry.registerComponent(appName, () => App);

my babel.config.js

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  Plugins:['react-native-reanimated/plugin'],//I added this line because of the 1st error 
};

my app.js

import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator} from '@react-navigation/stack';
import {createDrawerNavigator} from '@react-navigation/drawer';

//for stack
import Login from './pages/Login';
import Home from './pages/Home';
//for drawer
import cart from './pages/Drawer/cart';
import items from './pages/Drawer/items';

const stack = createStackNavigator();
const Drawer = createDrawerNavigator();

function MystackNav(){
  return(
    <stack.Navigator>
      <stack.Screen name='Login' component={Login} options={{headerShown:false}}/>
      <stack.Screen name='Home' component={Home} options={{headerShown:false}}/>
      <stack.Screen name='Drawer' component={MyDrawer}/>
    </stack.Navigator>
  )
}

function MyDrawer(){
  return(
    <Drawer.Navigator>
      <Drawer.Screen name='cart' component={cart}/>
    </Drawer.Navigator>

}

export default function App(){
  return(
    <NavigationContainer>
      <MystackNav/>
    </NavigationContainer>
  )
}

Answer 1

1.Update babel.config.js

  module.exports = {
    presets: [
      ...
    ],
    plugins: [
      ...
      'react-native-reanimated/plugin',
    ],
