Yes the create-react-app is not working.

It is a known issue, reported in official repository as well.

https://github.com/facebook/create-react-app/issues/17011

So if you want to continue to create the project using create-react-app. You can use this command. It won't have testing library setup.

npx create-react-app cra --template minimal

Points to remember: Do the following change in index.js file.

Replace

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

With

import ReactDOM from "react-dom/client";
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

The following worked for me.

In the directory where your project is located type in the following:

npm install -g [email protected]

Then I ran the command:

npx create-react-app <name of your project>

If there is anyone having this issue that you can not find your project when you

yarn create-react-app (name of project) npx create-react-app (name of project)

then just be sure that you are in the right directory.

use this command in your terminal

cd ..

now search the project name by

cd (project name)

you should find your directory here.

npx create-react-app .

( the .) means create project on this folder so you should manually create if you do that

I had the same problem and had to do the following:

npm uninstall -g create-react-app

npm uninstall create-react-app

After this I was able to create the app with:

npx create-react-app project-app

I just did it now after messing around with it all yesterday.

Installed react globally like people have said.

then I used 'git bash here' to open terminal in the directory i want

oddly, it worked when I removed npm. I know it's weird, I've never had to do that and it makes no sense but its working so:

create-react-app my-app-name

I'm on windows 10 by the way.

HAD the same problem. Running Node with cra. installed cra -g for starters.

npm install -g create-react-app

then downgraded react-scripts to version 2.1.8

npm install [email protected]

created a .env file in root directory and added this to it.

DB_HOST=localhost
DB_USER=root
DB_PASS=s1mpl3

SKIP_PREFLIGHT_CHECK=true

Then you do the typical delete node_modules folder and the package-lock.json file.(NOT PACKAGE.JSON!!!)

then:

npm install
npm start

This worked for me. Sorry I'm not more informative on why this worked for me. I'm still trying to understand why it didn't work in the first place.

It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production.

You’ll need to have Node >= 8.10 and npm >= 5.6 on your machine. To create a project, run:

npx create-react-app my-app

cd my-app

npm start

Note: npx on the first line is not a typo — it’s a package runner tool that comes with npm 5.2+.

Create react app provides more information regarding this.

It may be the problem of cache also, so can also try:

npm cache clean --force

Edit 1: This may be due to slow internet speed, Please check the internet and try again.

After no luck with updating my npm version and doing npm cache clean --force I ended up just doing a fresh install of node which fixed the issue for me.

I had similar issue while tried creating new react app with create-react-app, but related to some random JSON reading issues while installations like.. >= 5.0 || 4.0 ..

But the fix below solves multiple and similar issues.

First of all, make sure you have required or latest version of node installed.

npm install npm@latest -g

Before using create-react-app make sure you clean npm cache using npm cache clean --force

Now, is should be fine to create new react app with npx create-react-app tl-app or npx create-react-app . if you want to create current directory as project root.

Tried all the above methods but no luck:(

Step1 : Reinstalled Node js

Step2 : Check whether environment variables has been created. if not create one for nodejs,npm and composer

Step3: Also add "C:\Windows\System32" to the global PATH environment variable.

Step4: Then use "npx create-react-app my-app" to create react project

Step5: Run the commmand : cd my-app and npm start

Step6: It will work

What I did, is going to

C:\Users\mycomputerName\AppData\Roaming\npm\

I changed the name of this file

create-react-app.ps1

create-react-appOld.ps1

or you can delete it, then it worked fine

I had the same problem, and I solved it by:
1. update the npm version (npm install npm@latest -g)
2. clear the cache (npm cache clean --force)
3. create the react project (npx create-react-app todo)
(create-react-app was already installed)

The problem on my machine was caused by yarn. I am windows 10 and after uninstalling yarn using npm uninstall -g yarn, my script run correctly. So

Open terminal and type: npm uninstall -g yarn
Once done, close terminal and open new one
type create-react-app (app name) and this should create your app :)

Please note that the above steps assume that you already have node and react-cli installed on your machine.

I also experienced the same problem and SOLVED IT. This is what I did.

Restart your machine(computer)
Deactivate your anti-virus. I chose the "permanently" option
Open the terminal and run the "create-react-app" command again, It will definitely do the trick.
Activate your anti-virus
And get working :-)

Make sure you are not running any antivirus, stop/pause all antivirus or protection software.

You can also try

use create-react-app projectname --save
or create-react-app projectname --save-exact and start again

as the error suggests, you should use a newer version of node. You are using 8.9.4, you should probably use 8.12.0 LTS.
