Missing Attribute error

Sometimes you can get a missing attribute error due to `nixpkgs` channels missing from the channel list.

`nix-channels –list`

This should show a channel for `nix-darwin`, `home-manager` and `nixpkgs`. To add the required channels for `nixpkgs` run the following and then update all channels:

`nix-channel –add https://nixos.org/channels/nixpkgs-unstable nixpkgs`
