I ran into this issue as well. As a temporary fix I changed the command run by docker to: ```bash bash -c "rm state/db/*/*/*.lock; rm state/db/*/*.lock; hackage-server run --static-dir=datafiles" ```

This is something I've often been a little annoyed by with modules in the Nix ecosystem. Where the particular annoyance is that there are some, what I'll call, core options...

Could you add `--option experimental-features ca-derivations` to the flags you use when calling `darwin-rebuild`?

I added `android-file-transfer` to my `homebrew.casks` and it installed without issue, so at present I'm unable to reproduce this.

Pretty sure completions for javascript files are dependent on type information, and so you'll need to install the types for the modules your working with. Try `npm install --save-dev @types/node`....

I'm using a similar workaround right now. It would be nice if `nix-index` provided a native Fish version though. Maybe the easiest way would be to use [Babelfish](https://github.com/bouk/babelfish)? Version 1.1.0,...

You could try doing something like the trick I described here: https://github.com/bennofs/nix-index/issues/167#issuecomment-967764056

In case it's helpful to you or others, my current workaround is to set `nixpkgs` on my `NIX_PATH` to point to a [`nixpkgs.nix`](https://github.com/malob/nixpkgs/blob/master/nixpkgs.nix) file included in my Nix configs flake.

@LunNova, great point! I had forgotten that I was doing things the way I was so that the `nixpkgs` in `NIX_PATH` would support workflows that don't support flakes.

I agree to the extent there is something to fix here, it would be on `home-manager`'s end rather than `nix-darwin`'s end, though I'm not sure there is in fact something...
