error: Cannot build '...ghc-8.10.7-with-packages.drv'.

I tried this library when it was first released and it worked well. Today, when I returned to it after several months, I'm getting an error when I try to start the nix-shell.

> nix-shell

building '/nix/store/lpq25kiqxcgxpg1xvgkqj393r4h1bymy-hlint-3.2.8.drv'...

Here is my environment:

> nix-shell -p nix-info --run "nix-info -m"

 - system: `"aarch64-darwin"`
 - host os: `Darwin 24.6.0, macOS 15.6`
 - multi-user?: `yes`
 - sandbox: `no`
 - version: `nix-env (Nix) 2.30.2`
 - channels(root): `"nixpkgs"`
 - nixpkgs: `/nix/store/yakisxhc4jn2bqz45r1l6c7f4mrj83fv-nixpkgs/nixpkgs`

Were you using aarch64-darwin in both cases?

[wallacekelly-da]

It was the same laptop. 🤔

Here is the full CLI output, in case that is helpful.

Should be fine with #51 - we've updated to a newer GHC and newer nixpkgs

[wallacekelly-da]

Agreed. On branch release/0.1.0.2,...
