Dependency (auto-update) failing to install

Help

I’m very confused as to why a transitive dependency of my project is failing to build.
Prior to this error, lots of other packages have seemingly build fine and then…

I assume the problem is “sed: no input files”, but only because it’s the last item logged.
No idea what to try next really.

FWIW, the full nixpkgs.nix file I’m using is:

Haven’t really found my feed yet with nix, so this could be something very simple.
I’m using nix on a Mac M3.

In case it helps, there’s the -L | --print-build-logs flag.

Thanks mightyjam, I tried:
nix-build --verbose --show-trace

but that didn’t really shine any new light on things.

I’m supposing that the install phase just sees no files to install somehow.

I’ve just tried to use stack to build (with its nix integration). Although I didn’t expect much of a difference from just doing nix-build (especially as I cited the same nix configuration file in my stack.yaml nix stanza), it did seem to result in a different dependency to be tried, this time OneTuple, but with exactly the same problem (see below).

At this point I would place scripts into phases in order to debug. For example, postBuild = "ls -la".
