nix-shell fails with missing dependency error

[peterstuart]

I get the following error when I run nix-shell:

Setup: Encountered missing or private dependencies:

This is on NixOS, if that makes a difference.

Thanks for the report. I'm a bit surprised. Maybe your nixpkgs is out of date? Can you run nix-channel --update? (Possibly as root)

I could also try and pin a particular nixpkgs version. I'll do that later if I can and let you know.

@peterstuart I think #11 should fix this, if you can give it a try.

I ran nix-channel --update, but got the same error. I see the same error on your PR branch, too:

Thanks for looking into this! I haven't done Haskell development with Nix before, so I can't be much help.

@peterstuart I've looked into this a bit now, and the problem is indeed using a too old nixpkgs. Can you post nix-channel --list?

What I don't understand is why it doesn't work on that branch. Can you post the first few lines of mypkgs.nix? Probably I had some outdated commit on that branch, and I since pushed an updated version. Maybe you need to git checkout dev_nix2 && git fetch && git reset --hard origin/dev_nix2.

[peterstuart]

$ nix-channel --list
unstable https://nixos.org/channels/nixpkgs-unstable

mypkgs.nix:

{ compiler ? "ghc883"
# , nixpkgs ? import (builtins.fetchTarball "https://github.com/NixOS/nixpkgs-channels/archive/c59ea8b8a0e7f927e7291c14ea6cd1bd3a16ff38.tar.gz") {}
# If you have a nix-channel installed locally which you want to use, uncomment and possibly edit the following line, and comment the line above.
# , nixpkgs ? import <nixpkgs> {}
# Yet another possibility is uncommenting the next line, which will give you the latest stable release of nixpkgs. But you'll add a further change down, with http-client.
, nixpkgs ? import (builtins.fetchTarball "https://github.com/NixOS/nixpkgs-channels/archive/b83b54d0a8336746e4cd130bb7beb2ddd032ac87.tar.gz") {}
}:

I am on NixOS 20.03, so I did have to make the http-client change that you left a comment about in mypkgs.nix.

[turion]

@peterstuart Ah ok. Yes, I can reproduce that this doesn't work. 20.03 is too old. But that doesn't matter. In a nix-shell, you can have a different version. Can you revert your changes and uncomment the first commented line? That should work.

It might take a long time, but if you have cachix installed (or if you want to install it), you can save time by first executing cachix use manuelbaerenz.

[peterstuart]

That works, thanks!
