install nodejs mongodb and mongosh using a flake, and since mongosh is considered unfree software i added the last line
{
description = "Installing Nodejs with a flake";
inputs = {
nixpkgs-stable.url = "github:nixos/nixpkgs/nixos-23.11";
};
outputs = { self, nixpkgs-stable, ... }: with nixpkgs-stable.legacyPackages.x86_64-linux; {
devShells.x86_64-linux.TestingNodejsFlake = mkShell {
buildInputs = [
nodejs
mongodb
mongosh
];
}
{ nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"mongodb"
];
};
};
}
and i ran nix develop and i got this error:
error: error: attempt to call something which is not a function but a set
