I ran create-react-app and get this error message I did the followings like uninstalling global and so no but getting the same again and again.
You are running `create-react-app` 4.0.0, which is behind the latest release (4.0.1).
We no longer support global installation of Create React App.
Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app
The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/

Edit:
I've also tried the following:
Using npx instead. - but that's not working and is showing the above error message.
Uninstalled create-react-app using npm uninstall -g create-react-app before running npx create-react-app ahj-app - however that also doesn't work.
npm install -g create-react-app
Above worked for me.
Do not use npm to install "create-react-app" instead use npx this way:
npx create-react-app my-app
it will always use the lastest version
I solved this using the following command.
npm uninstall -g create-react-app
then again install
npm install -g create-react-app

please run the following command in Command Line:
npm cache clean --force
then run
create-react-app <project Name>
if you still getting the problem, uninstall the old and download new and remove all npm folders.
if still didn't help, you can switch from npm to yarn
npm install -g yarn
// Method 1
yarn global add create-react-app
create-react-app <projectname>
// Method 2 work on yarn 0.25+
yarn create react-app my-app
Hi thanks for reading this topic
I work with react I nowadays trying to learn ReactJS when install react new app show an error for uninstall react new project
what is my problem
in Command Terminal
npm ERR! Unexpected end of JSON input while parsing near
'...9.1","tslint-config
-p'
npm ERR! A complete log of this run can be found in: npm ERR!

I think it's version problem.
If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version
Quick Start
npx create-react-app my-app
cd my-app
npm start
For more clarification check this reactjs
I faced the same problem quite a few times.
Then used following commands, it worked for me
npm init
npm cache clean force
npx create-react-app my-app
cd my-app
npm start
I installed the latest version on Node JS with npm and cannot run create-react-app.
The following problem occurs:

From https://create-react-app.dev/docs/getting-started#creating-an-app
npx create-react-app my-app
(npx comes with npm 5.2+ and higher)
But you used
`create-react-app my-app`
If you use npm 5.1 or earlier, you can't use npx. Instead, install create-react-app globally:
npm install -g create-react-app
Now you can run:
create-react-app my-app
I was also not able to create a new app but when I follow these step
then it works for me.
After a few searches, I found this :
If you've previously installed create-react-app globally via npm install -g
create-react-app, we recommend you uninstall the package using npm uninstall -g
create-react-app to ensure that npx always uses the latest version.
So if you installed create-react-app with
npm -g install create-react-app
just run :
npm -g uninstall create-react-app
npx create-react-app
It should do the job
I was able to solve this problem by,
running
npm cache clean --force
then
npm create-react-app my-app
I had created reactjs project first I had installed globally create react app
npm install -g create-react-app
next, I try to project creation. am using this command
create-react-app react-firebase
while installing i had faced npm ERR! 404 Not Found: react-dev-utils#^5.0.2
error:
npm ERR! code E404
npm ERR! 404 Not Found: react-dev-utils#^5.0.2
How to fix it...
i tried this yarn add -g react-dev-utils#https://registry.npmjs.org/react-dev-utils/react-dev-utils-5.0.2.tgz (remove the "/-/" from the URL) and then run create-react-app my-app and it worked.
or if using npm try:
npm install -g react-dev-utils#https://registry.npmjs.org/react-dev-utils/react-dev-utils-5.0.2.tgz
The problem is npm is not able to find react-dev-utils in the registry server.
you can try different registries as mentioned here
Can't install any packages in Node.js using "npm install"
then you can solve this installing that package
npm install react-dev-utils#^5.0.2 -g
Something has changed in the registries. Explicitly adding the package didn't work for me, but flushing the lock files to remove reference to the old registry path did:
Yarn:
Delete yarn.lock
Run yarn
NPM:
Delete package-lock.json
Run npm install
