Why is npm start error creating react app - node.js

Question

I'm learning reactjs
I started with installing nodejs
and then ran these commands inside my project folder "React"
npx create-react-app hello-world
cd hello-world
npm start
but then instead of going to the browser i receive error:
npm ERR! missing script: start
npm ERR! A complete log of this run can be found in: npm ERR!
C:\Users\abc\AppData\Roaming\npm-cache_logs\2020-02-21T13_34_26_640Z-debug.log
PACKAGE.JSON CODE:
{
"name": "hello-world",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.12.0",
"react-dom": "^16.12.0",
"react-scripts": "3.4.0"
}
}
Help me solve this error i dont want it to demotivate me from learning React

Answer 1

npm scripts are missing inside your package.json file
npm ERR! missing script: start
Edit your package.json as follows:
{
"name": "hello-world",
"version": "0.1.0",
"private": true,
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build"
},
"dependencies": {
"react": "^16.12.0",
"react-dom": "^16.12.0",
"react-scripts": "3.4.0"
}
}

I was also facing almost same type of problem. But then tried
yarn create react-app my-app
in power shell with admin privilege which seemed to do the trick.
Also you’ll need to have Node >= 8.10, yarn >= 0.25+ on your machine
as the official doc suggests.
