'npx create app' not working - EPERM operation not allowed mkdir error

If you've tried to create a new app with npx create-app and received an error saying "EPERM operation not allowed mkdir", don't worry – you're not alone! This error can be frustrating, but there are a number of reasons why it might be happening and several possible solutions.

What causes the error?

There are a number of different potential causes of the "EPERM operation not allowed mkdir" error. Some of the most common include:

• Permission issues with the directory you're trying to create the app in
• Filesystem issues preventing the creation of new directories
• Problems with Node.js or npm itself

Depending on the root cause, there are a number of different steps you can take to try and resolve the issue.

Possible solutions

Here are some possible solutions to fix the "EPERM operation not allowed mkdir" error:

1. Run the command prompt as administrator: If you're running Windows, try opening the command prompt as an administrator. This can sometimes give the command the necessary permissions to create new folders.

2. Check your file permissions: Ensure that you have the necessary permissions to create new directories in the location you're trying to create your app. You can check this by right-clicking on the folder and selecting "Properties", then navigating to the "Security" tab.

3. Update to the latest version of npm: Sometimes, outdated versions of npm can cause issues like this. Try updating to the latest version using the command npm install -g npm.

4. Clear your npm cache: Run the command npm cache clean --force, then try rerunning the npx create-app command.

5. Check for filesystem errors: If you're on a Linux or macOS machine, run the command sudo fsck -fy to check your file system for errors. On Windows, you can attempt to repair the file system using the chkdsk command.

Hopefully one of these solutions will work for you! If not, there may be a more complicated underlying issue. Regardless, it's always a good idea to keep your system and apps up-to-date and to regularly check for errors in your file system to avoid issues like this.
