React, Uncaught ReferenceError: ReactDOM is not defined

Question

I am doing this Router tutorial.

My App.jsx file:

import React from \'react\';
import ReactDOM from \'react-dom\';
import { Router, Route, Link, browserH         


        

Answer 1

In this tutor this command "npm install react-router" does not save it in package.json file so modify and run command to "npm install --save react-router".
