Can't run SILE Flake from CI about sile-typesetter.github.io HOT 5 CLOSED

In score+=1 for debugging, I can at least reproduce this in NixOS!

$ docker run -it nixos/nix:latest
$ nix run --extra-experimental-features 'nix-command flakes' github:sile-typesetter/sile -- --version
error: attribute 'defaultApp.x86_64-linux' should have type 'derivation'

I don't understand why it works for me locally (Arch Linux w/ nix).

Adding the app name #sile to the command works both for me locally and in NixOS.

$ nix run --extra-experimental-features 'nix-command flakes' github:sile-typesetter/sile#sile -- --version
SILE v0.12.5-72b25f3-flake (Lua 5.3)

I will push that through as a fix to get the website updating, but I don't pretend to understand why.

I read this: NixOS/nix#6448 and I think your solution is:

diff --git i/flake.nix w/flake.nix

       };
       defaultApp = apps.sile;
     }

The change done in the newer nix version is the fact that nix run now searches for app.default attribute and not defaultPackage, so it seems.

Thanks! That wasn't quite the right syntax because ${sile} isn't set there and needed to be ${self.defaultPackage.${system}} instead, but it was close enough to get on the right track. I agree with that issue you linked, this error is too cryptic and points completely the wrong direction—at least for this specific cause.
