I got this error, when I run the same command

Error: EPERM: operation not permitted, mkdir 'C:\Users{USER_NAME}' command not found: create-react-app

[DarkDenims]

Bruh Same Error: EPERM: operation not permitted, mkdir 'C:\Users{USER_NAME}' command not found: create-react-app

i think it's because the user names has a character space " ", been trying to change the folder name and even user with local users and groups but it made things worse

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 :)

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

Please note this method might work but it is not the preferred method to solve this issue according to the create-react-app formal documentation we must not install this module globally. running the command npm install -g create-react-app will install create-react-app and the documentation advises us to avoid this and instead uninstall the package globally (by running npm uninstall -g create-react-app) and then resort to using npx. I have attached a picture below supporting my statement from the create-react-app documentation page: https://github.com/facebook/create-react-app . Please see my comment above highlighting the correct way to solve this 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.

OMG you helped a noob like me, thanks a lot

[VicodinAbuser]

@dhioputro This is not the recommended way of using create-react-app according to the React documentation and it may cause problems down the line.|

Same happened with me. I did the same, installed create-react-app globally and it started working but after a few days and a few tweaks and a few updates here and there it stopped working again.

After having to spend 2 hours digging I found this to be the more permanent solution.

Yeah, this is one way to get the short name. But you don't have to look for it all the time. By default, this is 6 letters followed by ~1. In my case, changing ABHI TRIPATHI to ABHITR~1 worked. Notice there are 6 letters. Since the Firstname is only 4 letters long so it also includes 2 letters of Lastname. Maybe the firstname you used was 5 letters long.

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 my live saver thank you for this tip next time I will only use firstname when configuring windows

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

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 :)

hy i am trying to create a new app using npx create-react-app my-app, but i am getting an error can someone help. I have also tried as administrator but still the same error.

$ npx create-react-app my-app npm ERR! code ENOLOCAL npm ERR! Could not install from "Malik\AppData\Roaming\npm-cache_npx\3724" as it does not contain a package.json file.

npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\Taabish Malik\AppData\Roaming\npm-cache_logs\2020-12-30T17_18_00_193Z-debug.log Install for [ 'create-react-app@latest' ] failed with code 1

[monticreativos]

This error is usually a problem that the "create-react-app" command is not recognized. Solution:

1. npm install -g create-react-app
2. npx create-react-app tunombredeaplicacion.

Remember that they must be in the root folder where you want to install the react app

[bilaliqbal1]

Thanks all of you. It's working.

Thank you very much. Been hours looking for a solution to this and yours worked in the first try :) Sahithi ma'am

Easiest solution to solving this issue is to run your cmd as an administrator. How do you run your cmd as an adm, just right click on the cmd and you will get the option.

@dhioputro This is not the recommended way of using create-react-app according to the React documentation and it may cause problems down the line.|

Same happened with me. I did the same, installed create-react-app globally and it started working but after a few days and a few tweaks and a few updates here and there it stopped working again.

After having to spend 2 hours digging I found this to be the more permanent solution.
