unable to run examples in React tictactoe tutorial about react

[Dranaxel]

I finally fixed it. I added import React from 'react'; in src/App.js

[sechi747]

Same for me. And it could work on codesandbox

[sebolio]

it also doesn't work when downloading and runing with npm start (after, of course, npm i)

[Antoniomora95]

@sebolio try to do this
import react
import React, { useState } from 'react';

and then, use react fragment this way

<React.Fragment> <div className="status">{status}</div> <div className="board-row"> <Square value={squares[0]} onSquareClick={() => handleClick(0)} /> <Square value={squares[1]} onSquareClick={() => handleClick(1)} /> <Square value={squares[2]} onSquareClick={() => handleClick(2)} /> </div> </React.Fragment>

not sure why it fails but looks to be related with the react version

Works fine in Codesandbox because its not the code - Its a firewall issue - works in one environment and not another . Any idea what domains the react tutorial attempts to reach on its way to codesandbox?

I'm encountering the same error as @sebolio on windows 10 - Debian 10 on WSL - node v19.8.1

@Antoniomora95 where are we supposed to add the line import React, { useState } from 'react';in ?

In index.js I get:

In app.js:

[strato67]

Was taking a look at react.dev, looks like it attempts to reach the Sandpack bundler assets through the CDN request URL: https://sandpack-cdn-staging.blazingly.io/...

CodeSandbox makes a request to Sandpack bundler through https://codesandbox.io/...

Check if your firewall blocks the CDN link by any chance?

As for this (#26429 (comment)), I don't know what we can do here — if your internet access is blocked, that's going to be a problem.
