Describe the bug

pnpm released version 11 two weeks ago. nixpacks currently supports up until v10, and defaults to v9 for unknown versions. This is now causing my builds to fail with:

2026-May-10 12:25:11.068184 #16 [12/16] RUN  pnpm install
2026-May-10 12:25:11.068184 #16 0.534  ERROR  packages field missing or empty
2026-May-10 12:25:11.068184 #16 0.534 For help, run: pnpm help install
2026-May-10 12:25:11.068184 #16 ERROR: process "/bin/bash -ol pipefail -c pnpm install" did not complete successfully: exit code: 1 

I'll file a PR to add support for v11 shortly.

@dennisameling I'd recommend looking at Railpack. Nixpacks is officially deprecated and we aren't going to be putting effort into supporting new language / package manager builds.

@iloveitaly thanks for your reply. I created the PRs here because Coolify still defaults to Nixpacks for builds. They added Railpack support as a beta feature in 4.1.0 two weeks ago, but it has some implementation-specific bugs like this one. Personally I'll be using Railpack moving forward, but some other Coolify users might stick with Nixpacks for a little bit longer until Railpack support hits GA.

we aren't going to be putting effort into supporting new language / package manager builds.

Shall we close this issue then, or leave it open in case other Coolify users might find this and be informed about the status?
