create-react-app failed And Many ways wont work for me

Does anyone know how to fix this problem?
I have tried several ways to do it but still didnt manage to create a successful create-react-app. Here are few solutions I have tried but all failed.
npm uninstall -g create-react-app, npx clear-npx-cache, npx create-react-app my-app
npm rm -g create-react-app
npm install -g create-react-app
npx create-react-app my-app
uninstalling node and install back.
deleting the files rm -rf /usr/local/bin/create-react-app
creating project with latest
create the project using yarn
Create projects with powershell
All of the above still did not managed to create my react app succesfully. Any idea why?
This is the closest I can get which create other required files without src file and cant npm start
Problems

The command `npx create-react-app my-app` does not create an application file

I want to install create-react-app. I'm using the command: npx create-react-app my-app. I can see the following information in the console:
Installing packages. This might take a couple of minutes. Installing react, react-dom, and react-scripts with cra-template ... added 1374 packages in 4m 163 packages are looking for funding run npm fund for details
and nothing is happening.
node and npm are the newest
In the folder I just created, I can only see node-modules, package, package-lock. I don't have a file src. How to solve this problem?

Try with these steps :
npm rm -g create-react-app
npm install -g create-react-app
npx create-react-app my-app
Update
install yarn (https://yarnpkg.com/getting-started/install)
install CRA with yarn!
yarn create react-app my-app

yarn error while creating react application. Existing answer not helping [duplicate]

I tried installing create-react-app using npm i create-react-app, npx create-react-app new-app and npm init react-app new-app, but I keep getting this error message:
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.
How can I fix this?

This worked for me:
npx create-react-app#latest your-project-name --use-npm

According to the create-react-app docs, create-react-app should not be installed globally:
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 or yarn global remove create-react-app to ensure that npx always uses the latest version.
This is even stated in the error message you recieved:
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.
You must uninstall create-react-app with npm uninstall -g create-react-app.
Then each time you want to create a new React app with create-react-app, use the command npx create-react-app my-app.
So to fix the error you're getting, uninstall create-react-app globally, update npm, clear the cache, and retry creating the app.
Run this in your terminal:
npm uninstall -g create-react-app && npm i -g npm#latest && npm cache clean -f && npx create-react-app#latest my-app --use-npm

I got
You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0).
We no longer support global installation of Create React App.
so I simply called the package with an explicit version:
npx create-react-app#5.0.0 app-name

I also faced this issue after they released v4.0.2.
They have mentioned 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 or yarn global remove create-react-app to ensure that npx always uses the latest version.
I resolved the issue by following the below steps:
Uninstall create-react-app v4.0.1:
# for npm:
npm uninstall -g create-react-app
# for yarn:
yarn global remove create-react-app
You are not required to install create-react-app in your local directory, so if you do not want to do this then move to step 3. If you want to do this, install v4.0.2 without using the global flag (-g or --global) using the below command:
# for npm:
npm i create-react-app
# for yarn:
yarn add create-react-app
You can now create a new React app using the below command:
# for npx:
npx create-react-app my-app
# for npm:
npm init react-app my-app
# for yarn:
yarn create react-app my-app

I also face the same problem but the problem gets solved when I uninstall the create-react-app globally and then again install it globally.
Uninstalling Command:
npm uninstall -g create-react-app
installing Command:
npx create-react-app my-app
if you have an older npm version (npm version < 5.2) then use this command :
npm install -g create-react-app
it solved my problem I hope it will solve yours

Updating NPX worked for me. Suggestions on this page didn't do the trick but might have contributed.
npm update npx

What worked for me was:
npm uninstall -g create-react-app
And then:
npm i create-react-app # or yarn add create-react-app
I also updated the Node version.

Uninstalling create-react-app globally via npm and reinstalling without the global flag did not work for me.
npm uninstall -g create-react-app
npm install create-react-app
I was on node version 15.2.0. I upgraded to the latest stable node version 15.3.0 via nvm.
nvm install node
Then I installed create-react-app again (no global flag).
npm install create-react-app
I was then able to successfully create a new react app.
npx create-react-app my-app
EDIT: The above will install create-react-app to your current directory. To be clear, after uninstalling create-react-app globally I was no longer able to create an app via npx and received the same original error message. The best solution I've found so far is to run npm install -g npm#latest which downgraded my npm version from 7.0.14 dev build to 6.14.9 LTS build and allowed me to create the react app via npx without issue.

npm uninstall -g create-react-app
Although the uninstall command ran successfully , it was not able to uninstall create-react-app, so i kept running into the same error again and again
This finally worked for me npx create-react-app#latest my-app --template typescript

After create-react-app > 4.0.1 use these commands
npm
npm init react-app my-app
yarn
yarn create react-app my-app
Getting Started | Create React App Docs

I have nvm installed, and while using the command npx create-react-app my-app; I got this error:
You are running `create-react-app` 4.0.1, which is behind the latest release (4.0.2).
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
I confirmed that I did not have create-react-app installed globally in my nvm global directory.
I solved issue by specifying the version of the package
npx create-react-app#4.0.2 my-app

For me it was the issue with my npm version. So i did this:
npm install npm#latest -g
Now npx create-react-app app_name works.

I had to downgrade to the latest stable version of node with n in order to make it work.
sudo n stable
Just to make it clear, I never installed it globally, I just had this problem after upgrading node.

There are two different causes of this error:
You have create-react-app installed globally. Use this command to find out if you do: npm list -g --depth 0. If so, follow the instructions in the error message to uninstall it globally.
You are using node v15.0.0+. Use NVM to switch to the LTS nvm use --lts and then run create-react-app. After that you can switch to v15.0.0+ and continue working. (If you do not have NVM installed, here is how you can install it: https://github.com/nvm-sh/nvm)

For me I got the same error even though create-react-app was installed in a parent directory, not globally. So I ran npm uninstall create-react-app without the -g flag and it worked.

Using Git Bash on Windows i run into the same issue today
npx create-react-app appname
even didn't worked after i uninstalled the global installation with
npm uninstall -g create-react-app
What solved the problem for me was to clean the npm cache with the following command
npm cache clean -f

This worked for me.
sudo npm uninstall create-react-app -g
sudo npm install create-react-app#5.0.0 -g
npx create-react-app my-app

I know I'm late to the party, but here are my two cents to help you. This is how I made it worked
Uninstall Global create-react-app installation
npm uninstall -g create-react-app
Now clear the npx cache by
npx clear-npx-cache
Now try to create the application; if you still get the error saying we don't support create-react-app, change the directory to create the application
run
npx create-react-app my-app
This is how I made this worked

i was facing same issues a while ago
npx create-react-app#latest app-name
worked for me

Solution-1: Update your node package manager by using the command below.
npm install -g npm#latest
npx create-react-app my-app
Solution-2: Run your PowerShell as administrator and run the commands. Something this will not work
npm uninstall -g create-react-app
npm install -g create-react-app
//OR
npx create-react-app my-app
Solution-3: The permanent solution is to uninstall node.js and NPM and install them once again.
enjoy

use this :
npm install create-react-app

I ran into this myself today and my root cause is likely very rare but perhaps it will help someone else.
I had an npm registry defined in my .npmrc which my work requires us to use. Turns out my work mirror didn't have 4.0.1 and something in create-react-app must phone home and run a version check.
If you have a registry defined run npm view create-react-app to check the latest version.

After exploring the Github issues a bit I found a solution to this problem that was posted, which doesnt require downgrading node or npm.
I'm using Ubuntu on WSL2 so keep in mind locations might vary. The problem comes from npm having cached a global installation of create-react-app with npx that is v4.0.0 which doesnt show when you use npm view create-react-app.
If you find your npm cache which for me was located in ~/.npm/_npx/ folder, you will find folders with hashed names from all your global installs where you have used npx previously.
If you look through each of them for example with cat [hash]/package.json and note down the hash of any that contains create-react-app. Now go ahead and manually edit the package.json files to bump the version of create-react-app to 4.0.1 - and afterwards remove it from node modules with rm -rf [hash]/node_modules/create-react-app.
After this if you go back out and try to run npx create-react-app my-app it will prompt you to install 'create-react-app' as normal and should work fine, and now npx will have cached the correct version of 'create-react-app' so you wont have the issue again either. And you can use whichever version of node and npm you like.
If you're on Windows or Mac you have to figure out where the cache is located, as I don't know - but the rest of the steps should be the same.

i didn't have any global create-react-app i just did npm uninstall -g create-react-app and then i did npm install create-react-app

I ran into the same problem and the error isn't quite as explanatory as it should be. I fixed it by updating npx itself.
Please type in npm update npxin your terminal to resolve the problem.
After that you can type in npx create-react-app "your preferred project name" to create your react project.

I've uninstalled create-react-app globally also from yarn
npm uninstall create-react-app -g
And the reinstalled create-react-app
npm i create-react-app
or another way is:
npm create-react-app#latest my-app
npm create-react-app#4.0.2 my-app

The other answers didn't work for me. Trying to uninstall globally, for instance, might work to uninstall it but the error persists. It persisted across new installations of Node, and so on.
However, the following seems straightforward and worked for me:
Go into some fresh folder, in which you'll create the app, so that it doesn't already know about create-react-app.
yarn add create-react-app
yarn run create-react-app myapp

SOLUTION:
Step # 1: Remove globally the create-react-app package:
npm uninstall -g create-react-app
Step # 2: Install again globally the create-react-app package:
npm install -g create-react-app
That will install the version 5.0.1 (or higher). To check if it was properly installed, run this on the terminal:
npm list -g
Result:

And then try again to create the react app, using the sentence:
npx create-react-app <project_name>
And then it will work.

This worked for me
npm uninstall -g create-react-app
then
npm install -g create-react-app

I uninstalled node.js and reinstalled it using windows installer. Now npx create-react-app command works like a charm.

create-react-app is not working since version 4.0.1 how to remove the old version and install the new version of it

When I enter npx create-react-app ./ command for creating a react app it gives the following warning and not creating the 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/
When I enter - npm uninstall -g create-react-app command, and then I entered gain npx create-react-app ./ again gives the above error
Updated
I uninstalled with npm uninstall -g create-react-app
and again installed with npm install -g create-react-app
and then created my app with npx create-react-app ./
I already created a folder inside that folder I created my project so no need to gave project name I used ./ it will create your project inside that folder

I uninstalled with npm uninstall -g create-react-app
and again installed with npm install -g create-react-app
and then created my app with npx create-react-app ./
I already created a folder inside that folder I created my project so no need to gave project name I used ./ it will create your project inside that folder

You could try the following:
Uninstall with npm uninstall -g create-react-app
Install with npm install -g create-react-app and try again
You could also try using npm init: npm init react-app myapp

module npm file doesn't appear to me

I am trying to follow with pluralsight tutorial and he wrote npm install on the terminal, then a file called npm module is installed on the folder he specified. when I try to install npm this appears to me in the terminal, and the directory which Im trying to install npm on it contains only one document called package-lock.json enter image description here

npm install uses the package.json to install the necessary packages
I can see when you ls, there's no package.json in the directory, just the package-lock which is created where ever you run npm install
Make sure you run the npm install from the same directory the package.json in contained in

the problem is solved, I think that I download the web-dev-starter folder twice by mistake.
