Nix-shell https://holochain.love | error: error: cycle detected in build of '/nix/store/3xz7l4hc8gmlpz7062v2khacy78q1900-niv-0.2.19.drv' in the references of output 'bin' from output 'out'

Cheers. Trying to get Holochain up and running for the first time. I’ve run nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/nixos-21.11.tar.gz -p cachix --run "cachix use holochain-ci with success.

But then nix-shell https://holochain.love returns the following error (after a lot of derivations being built):

**error:** **error:** cycle detected in build of '**/nix/store/3xz7l4hc8gmlpz7062v2khacy78q1900-niv-0.2.19.drv**' in the references of output '**bin**' from output '**out**

I’ll include the entire list of built derivations, if helpful, but it’s a mighty list.
