Failed to load Home Manager Options cache file: Os { code: 2, kind: NotFound, message: "No such file or directory" }

[bbigras]

I don't know if it's related but I'm using home-manager.users to use home-manager in my configuration.nix. And I'm using niv so I don't have any home-manager channel.

For me it was because i didn't had home-manager in my nix channels see here

maybe this could be checked and a sane error could be written

fixed this by doing

$ nix-channel --add https://github.com/rycee/home-manager/archive/master.tar.gz home-manager
$ nix-channel --update

[mlvzk]

I disabled the "Failed to load Home Manager Options cache file" error and added a message recommending to run mhhf's snippet when building home-manager options cache fails.

In the future I might attempt at supporting home-manager installed through configuration.nix without this workaround.

[bbigras]

It's weird, I still see "Failed to update Home Manager Options".

@bbigras could you try running this command:

find "$(nix-build -E "{ pkgs ? import <nixpkgs> {} }:
            let
                hmargs = { pkgs = pkgs; lib = import (<home-manager/modules/lib/stdlib-extended.nix>) pkgs.lib; };
                docs = import (<home-manager/doc>) hmargs;
            in (if builtins.isFunction docs then docs hmargs else docs).options.json")"

and paste the output?

[mlvzk]

Strange. I can't reproduce your error, not sure if I'll be able to help. Maybe try running it in a new terminal so your environment variables are updated.

[bbigras]

Sorry. Rebooting fixed it. I tried in a new terminal but maybe I had to log out and log back in. Thanks.
