Error when using nix-shell, looking for help

[feiyax]

Hi, I'm trying to build the project, and i just had a fresh install of nix. I haven't used nix before.

I got this error when launching nix-shell from the repo directory. I'm not sure if that's an issue with nix itself or something related to this project. Any help or pointer is appreciated. Thanks!

$ nix-shell  --show-trace

This looks like #68. It seems to work with the 21.05 channel so I suggest adding -I nixpkgs=channel:nixos-21.05 to your nix-shell command and see how you go.

Should be fixed on 0.8.0. Unfortunately I cannot test it. Feel free to reopen if the issue persist.
