[Nix-dev] Error installing hydra

[Bjørn Forsman]

Hi,

I'm following the documentation on how to install hydra[1], but I get
this error:

$ nix-channel --add http://hydra.nixos.org/jobset/hydra/trunk/channel/latest
$ nix-channel --update
$ nix-env -i hydra
installing `hydra-0.1pre1271-9f027b2'
don't know how to build these paths:
  /nix/store/7vlizjmz662s6pifyh596n3b5zacy7iv-hydra-0.1pre1271-9f027b2
error: path `/nix/store/7vlizjmz662s6pifyh596n3b5zacy7iv-hydra-0.1pre1271-9f027b2'
does not exist and cannot be created

Any ideas?

Best regards,
Bjørn Forsman
