Adding "--pure" reveals the issue: > > | #! /usr/bin/env nix-shell > | #! nix-shell --pure -i runghc -p "haskellPackages.ghcWithPackages (p: > [p.HTTP])" The problem is that quoted arguments don't work here at the moment. As a workaround, you can put this in the script: #! /usr/bin/env nix-shell #! nix-shell -i runghc ./script.nix and this in "script.nix": with import (fetchTarball https://github.com/NixOS/nixpkgs-channels/archive/nixos-unstable.tar.gz) {}; runCommand "dummy" { buildInputs = [ (haskellPackages.ghcWithPackages (p: [p.HTTP p.tagsoup])) ]; } "" -- Eelco Dolstra | LogicBlox, Inc. | http://nixos.org/~eelco/ _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
