Unable to resolve module 'react-navigation'

This error means that either you haven't installed the react-navigation module or that you have installed the module but didn't re-built your project using react-native run-android or react-native run-ios.

1. Install react-navigation module.
2. Re-build your project.

Follow this steps:

1. Install React Navigation npm install react-navigation

2. Install Dependencies expo install react-native-gesture-handler react-native-reanimated react-native-screens react-native-safe-area-context @react-native-community/masked-view

3. Install React Navigation Stack npm install react-navigation-stack @react-native-community/masked-view

4. Start the app and clear cache with npm start -c

We need to install the following dependencies:

npm i react-navigation @react-native-community/masked-view react-native-gesture-handler react-native-reanimated react-native-safe-area-context react-native-screens

In code import the following:

import {createAppContainer} from 'react-navigation'; 
import {createStackNavigator} from 'react-navigation-stack';

You have to just install the missing module ex.

npm install react-navigation

Then restart with

npm start
