Trouble installing React for the first time?

Question

React

Hello, I'm starting to learn React, and I ran into a problem installing it. The problem is this: when I enter the command

npx create-react-app my-app

, the following happens: a very long download starts, then it gives the following:

Creating a new React app in /home/sasha/my_project/react/my-app.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts with cra-template...

Aborting installation.
  npm install --save --save-exact --loglevel error react react-dom react-scripts cra-template has failed.

Deleting generated file... package.json
Deleting my-app/ from /home/sasha/my_project/react
Done.

When I enter through sudo:

sudo npx create-react-app my-app

it immediately gives out:

sh: 1: create-react-app: Permission denied

What to do? Help me please

Answer 1

sudo npx create-react-app my-app

Can't with sudo

npm ERR! code FETCH_ERROR
npm ERR! errno FETCH_ERROR
npm ERR! invalid json response body at https://registry.npmjs.org/@rollup%2fplugin-replace reason: Unexpected end of JSON input

Apparently something with the network, since such an error. Try visiting https://registry.npmjs.org/@rollup%2fplugin-replace yourself and see the logs
