error: Package ‘nvidia-x11-570.144-6.12.28’ in /nix/store/x9wnkly3k1gkq580m90jjn32q9f05q2v-source/pkgs/os-specific/linux/nvidia-x11/generic.nix:320 has an unfree license (‘unfreeRedistributable’), refusing to evaluate.
a) To temporarily allow unfree packages, you can use an environment variable
for a single invocation of the nix tools.
$ export NIXPKGS_ALLOW_UNFREE=1
Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
then pass `--impure` in order to allow use of environment variables.
b) For `nixos-rebuild` you can set
{ nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.
Alternatively you can configure a predicate to allow specific packages:
{ nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"nvidia-x11"
];
}
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowUnfree = true; }
to ~/.config/nixpkgs/config.nix.
