Open your IDE's terminal and type this :

npm install -g create-react-app

Followed by: npx create-react-app <Any name that you want>

Cheers,

[masfikalam]

Try installing it globally first, using the command npm install -g create-react-app

And then, you can create your app using the command, npx create-react-app <Name of your app>

Hope this helps :)

Thank you so much!!!

This error is caused by having a space in your User name (i.e the name of your machine) for instance my machine name is Themba Alex, npx has an issue when such is the case, the solution to this is to open your terminal and run this command: npm config edit afterward go to every line that is starting with ;cache=C:\Users\Themba Alex\AppData\Roaming\npm-cache, remove the ; and remove the space on your username, write the first 6 letters and add "~1" i.e ;cache=C:\Users\Themba Alex\AppData\Roaming\npm-cache will now be cache=C:\Users\Themba~1\AppData\Roaming\npm-cache this will solve the issue

After a lot of digging and coming to this, I thought this would solve my problem but it isn't solving my problem. Even after changing Firstname Lastname to Firstname~1 and to Firstname~Lastname I am getting the same error. Error: EPERM: operation not permitted, mkdir 'C:\Users\Firstname~Lastname' command not found: create-react-app

I found the solution to this. Instead of just changing Firstname Lastname to Firstname~1 or Firstname~Lastname , check what the short name for your Username directory is. You can do this by opening the CMD as an administrator and running dir /x in the parent folder of the folder whose short name you're trying to find. In this case since you want to know the short name to your Firstname Lastname folder, the parent folder will be C:/Users. So go to C:/Users and run dir /x. You'll find the short name of your Firstname Lastname folder. It may not necessarily be Firstname~1. In my case, it was FirstnameL~1. After this you can run npm config set cache "C:/Users/<shortname-you-found-with-dir/x>/AppData/Roaming/npm-cache" --global. Now you should be able to run npx create-react-app my-app without any issue.

You are Maseiah!!

Hope this helps :)

First of all, it is not a recommended solution which you can see from the official docs

I'm on Windows 10 64-bit Pro and let me explain how I made it work step by step.

Note my username for my machine is Assad Ullah Chaudhry

You got spaces in your username that's why it is not working for you

Follow the steps to make it work:

1. Open up power shell or any command line program go into C:\Users
2. Once you are in C:\Users, type dir /x and you should see something like this.
3. You can see my short name is ASSADU~1 and in your case it would be different. Now run this command npm config set cache "C:/Users/<your-shortname-goes-here>/AppData/Roaming/npm-cache" --global. With my short name, this command looks like this npm config set cache "C:/Users/ASSADU~1/AppData/Roaming/npm-cache" --global just so you know the final look of it before running it.
4. Final step, run npx create-react-app my-app and that's it.

Hope it helps!

This one worked for me. First go to C:/Users and get your truncated username from there and in cmd (admin level permission), do these

npm config edit afterward go to every line that is starting with ;cache=C:\Users\Themba Alex\AppData\Roaming\npm-cache, remove the ; and remove the space on your username, write the first 6 letters and add "~1" i.e ;cache=C:\Users\Themba Alex\AppData\Roaming\npm-cache will now be cache=C:\Users\Themba~1\AppData\Roaming\npm-cache this will solve the issue

[ishaiknadeem]

I was facing the same problem for 3 days and got this solution for it...

It's because of old files lying in your c drive:

Follow the steps below and try, It will work for sure.

problem:

npm ERR! Errno: -4048, npm ERR! code: ‘EPERM’, npm ERR! syscall: ‘scandir’,

solution:

Uninstall node with node uninstaller ( find it from run cmd )

Then...

Delete the npmrc file and delete the C:\Users\Administrator.npmrc file ( if don't find leave it )

Delete npm-cache folder from - C:\Users\Administrator\AppData\Roaming

Delete npm folder from - C:\Users\Administrator\AppData\Roaming

Restart your system and install fresh NodeJS and run this command in cmd: npm cache clean -–force to ensure the cache is cleared.

That's your ready to go now...

The dir /x command not work on power shell, use cmd

[assadullahchaudhry]

Nothing here solved my issue. Am frustrated right now thou.

@Akintola-Stephen Don't worry. Let me help you out with this :)

I'm on Windows 10 64-bit Pro and let me explain how I made it work step by step.

Note my username for my machine is Assad Ullah Chaudhry You got spaces in your username that's why it is not working for you Follow the steps to make it work:

1. Open up power shell or any command-line program go into C:\Users
2. Once you are in C:\Users, type dir /x and you should see something like this.
3. You can see my short name is ASSADU~1 and in your case it would be different. Now run this command npm config set cache "C:/Users/<your-shortname-goes-here>/AppData/Roaming/npm-cache" --global. With my short name, this command looks like this npm config set cache "C:/Users/ASSADU~1/AppData/Roaming/npm-cache" --global just so you know the final look of it before running it.
4. Final step, run npx create-react-app my-app and that's it.

Hope it helps!

@Angel-Ponce make sure to close and reopen your powershell. It's a solid workaround.

Try installing it globally first, using the command npm install -g create-react-app

And then, you can create your app using the command, npx create-react-app Thanks a lot, it works. And it will help to a beginner in react.

This error is caused by having a space in your User name (i.e the name of your machine) for instance my machine name is Themba Alex, npx has an issue when such is the case, the solution to this is to open your terminal and run this command: npm config edit afterward go to every line that is starting with ;cache=C:\Users\Themba Alex\AppData\Roaming\npm-cache, remove the ; and remove the space on your username, write the first 6 letters and add "~1" i.e ;cache=C:\Users\Themba Alex\AppData\Roaming\npm-cache will now be cache=C:\Users\Themba~1\AppData\Roaming\npm-cache this will solve the issue

After a lot of digging and coming to this, I thought this would solve my problem but it isn't solving my problem. Even after changing Firstname Lastname to Firstname~1 and to Firstname~Lastname I am getting the same error. Error: EPERM: operation not permitted, mkdir 'C:\Users\Firstname~Lastname' command not found: create-react-app

I found the solution to this. Instead of just changing Firstname Lastname to Firstname~1 or Firstname~Lastname , check what the short name for your Username directory is. You can do this by opening the CMD as an administrator and running dir /x in the parent folder of the folder whose short name you're trying to find. In this case since you want to know the short name to your Firstname Lastname folder, the parent folder will be C:/Users. So go to C:/Users and run dir /x. You'll find the short name of your Firstname Lastname folder. It may not necessarily be Firstname~1. In my case, it was FirstnameL~1. After this you can run npm config set cache "C:/Users/<shortname-you-found-with-dir/x>/AppData/Roaming/npm-cache" --global. Now you should be able to run npx create-react-app my-app without any issue.

I was facing the same problem for 3 days and got this solution for it...

It's because of old files lying in your c drive:

Follow the steps below and try, It will work for sure.

problem:

npm ERR! Errno: -4048, npm ERR! code: ‘EPERM’, npm ERR! syscall: ‘scandir’,

solution:

Uninstall node with node uninstaller ( find it from run cmd )

Then...

Delete the npmrc file and delete the C:\Users\Administrator.npmrc file ( if don't find leave it )

Delete npm-cache folder from - C:\Users\Administrator\AppData\Roaming

Delete npm folder from - C:\Users\Administrator\AppData\Roaming

Restart your system and install fresh NodeJS and run this command in cmd: npm cache clean -–force to ensure the cache is cleared.

That's your ready to go now...

If you still face a problem feel free to get in touch with me @ishaiknadeem username on any platform
