If the file does not exist you have to create it. It should work.

Not sure what directory you are in (folder).  Maybe post back (use pwd).  None the less, you probably don't have the nix.conf file made in /etc/nix directory?  Try this on how to make one: https://www.punkbit.com/hacking/plutus-developer-environment-setup-on-macos-monterey/

It’s because the folder .config does not exist yet, so you cannot create the nested folder nix

So you run this instead

`mkdir -p ~/.config/nix`
