# NousResearch/hermes-agent · Nix build handling of extraPythonPackages overlapping with sealed venv

## Open now

- 1 issue, 1 PR open on GitHub.
- #43810: \[Bug\]: Nix build fails when extraPythonPackages contain deps already in sealed venv (e.g. requests, numpy, pillow)
- PR #43821: fix(nix): filter plugin deps already in sealed venv instead of failing build

These members center on Nix builds where extraPythonPackages include dependencies already present in the sealed venv (e.g. requests, numpy, pillow). One item is a bug report, and two are pull requests proposing different approaches: filtering the overlapping deps, or downgrading the collision check to a warning.

## TL;DR

- 3 member(s): 1 open issue(s), 0 closed issue(s), 1 open PR(s), 0 merged PR(s), 1 PR(s) closed without merging.
- No fix has been merged to main; one or more PRs were attempted (see below).
- **Recommended:** review the prior/competing PR(s) below. A fix was attempted but not merged; your case may extend or revive that work.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
