This happens on more than one of my computers. One is macOS 14, the other is macOS 13.

Hey @magnusviri! Good to see you back, hope you're doing well.

The error you're encountering is due to insufficient permissions when trying to access the /.git directory. This is happening because the black command is trying to find the root of the project by looking for a .git directory, starting from the current directory and moving upwards. When it reaches the root directory / and tries to access /.git, it fails because of insufficient permissions.

This issue can be resolved by ensuring that you're running the pkgx black command from within the directory of the project you're trying to format with Black, and not from the root directory /.

If you're already running the command from within the project directory and still encountering this issue, it could be due to an incorrect setup of your environment. In this case, you might want to check the permissions of your project directory and its parent directories.

Here's a command you can use to check the permissions of the current directory and its parent directories:

name=$(pwd); while [[ "$name" != "" ]]; do ls -ld "$name"; name=${name%/*}; done

This command will list the permissions of the current directory and each of its parent directories. If you see any directory that doesn't have read and execute permissions for your user, you can add them using the chmod command. For example, to add read and execute permissions for the user on the directory /path/to/directory, you can use the following command:

chmod u+rx /path/to/directory

Please note that you might need to use sudo with the chmod command if you don't own the directory.

I hope this helps! If you have any further questions, feel free to ask.

I think this is a black bug. Nevermind.

Yeah, I just confirmed it's a black bug.
