Mistake running makes

What happens

I am trying to run the commands that have to do with makes as they are m . or m. /LinitGitMail but I get an error

What do you understand or find about that problem

I already uninstalled and installed Nix or so I think, but I still get that error

I need help with

I would like to know if the error that appears is because NIX is not installed correctly

Remember that to execute “makes” you must be in the root of the repository, otherwise it will not be able to recognize the commands.
