error: The prefix 'nix' is reserved for internal use by Lix in the Nix search path, its usage is deprecated and will be forbidden in the future.
       Use --extra-deprecated-features nix-path-shadow to silence this error.
       This is due to adding 'nix=nix-shadow' in the Nix search path, either through the environment variable 'NIX_PATH' or by passing the flag -I to the nix invocation.
