Attempted to download and build the discourse nixpkg but it failed due to a seeming pnpm dependency error: ERR_PNPM_INVALID_DEPENDENCY_NAME Refusing to place a dependency under /build/source/frontend/discourse-types/node_modules with the invalid alias "@types/@glimmer__component" ERROR: pnpm fai…

Thanks for the report! I took a look, and this appears to be a pnpm version mismatch in the Nix package rather than a problem with the dependency hash. Discourse v2026.1.4 declares pnpm@10.28.0, while the Nix expression uses the moving pnpm_10 package, which currently resolves to 10.34.4. That newe…

The thing is, only Debian/Ubuntu are supported, not Nix. Is this for a development environment or for production?

this is just downloading the discourse package from nixpkgs using the nix package manager. Derivations work by essentially cloning and building a package directly from the source. I was just ephmerally installing a package like I would any other nixOS. Not specifically for dev or production, really…

Interesting. I believe the package isn’t officially by Discourse. A quick glance at the Maintainers does not list any member of the Discourse team that I have heard of. Plus, no Documentation about this AFAIK. For reference: this plugin I think

ah yes that is the nixpkg maintainer(s) the actual source is in the `let in` block line 55: let version = "2026.1.4"; src = fetchFromGitHub { owner = "discourse"; repo = "discourse"; rev = "v${version}"; sha256 = "sha256-kQYDKZIMsWByuCZQfUlwhoIew5QykVylRMh6xvrHIBY="; }; in …

Also you don’t need to commit to the full nixOS to test this the nix package manager is available for nearly any machine `nix-shell -p discourse` where the `nix-shell` starts a shell where whatever package(s), `-p`, are now available on the system. once the shell is closed those packages are no l…

testing to see if this thread has been locked as I can’t see one of my most recent edits. maybe the edit needs to be approved to display in the post

no worries! thanks for the clarification. The reason I suspected some approval process is because I’d made this edit and didn’t see it come up on my end: [image] I still see just the text on the left side E: it just appeared

I may have jumped the gun on marking this solved as I haven’t actually tested that lol Nixpkgs allows for overlays and overrides of it’s packages locally. I can try to implement those changes to the derivation myself when I get some time and report back my findings

This is as far as I got: let nixpkgs = fetchTarball "https://github.com/NixOS/nixpkgs/tarball/nixos-26.05"; pkgs = import nixpkgs { config = { }; overlays = with pkgs; [ (final: prev: { discourse = prev.discourse.override (oa: { pnpm_10 = oa.pnpm_10.overrideAttrs…
