I was having the same problem after upgrading to yarn 3.3.0, and I followed Rodrigo Merlone's answer above by searching

ls -a | grep -E 'yarn|package'

in each of my directories until I discovered .yarn files, package-lock.json files and others in my home directory. I must have installed these through CLI accidentally while trying new things.

After deleting these files, I can run

yarn create react-app my-app-name

in my desired folder and it works!

I think you have an old node version. You need to update node to Latest LTS Version in your system (windows or etc.)

experience similar issue

use npx create-react-app app-name instead of yarn after which you can install other packages and libraries using yarn.

In you /home/flovet-stack/ folder, run ls -a | grep -E 'yarn|package' command. If you see there are a few folders and files such as

  • package.json
  • package-lock.json
  • .yarn or yarn.lock or any yarn folder and file

Delete these files.

Did you by any chance happen to try and change yarn version (yarn set version <version>) while in that folder? If you did, that's what might've happend. Set the version of yarn in your project or workspace folder only to avoid this in the future, as instructed here

I've had a similar problem.

yarn create react-app ... had problem with file package.json that was in my $HOME directory.

After removing it, command yarn create react-app ... was successfull.

Note that file package.json in my home dir was populated with following declaration:

{
  "packageManager": "[email protected]"
}

I will investigate if this file was needed somehow and update this post if it was.

do you have a yarn.lock in that directory/folder? If so, try to delete that and run the command again.
