file: dependencies cannot resolve a workspace package peer

[mwolson]

• Aube: 2.6.1, Linux x64
• Pnpm: 12.8.1
• Repro: https://github.com/mwolson/tmp-aube-issues/tree/main/file-dep-workspace-peer-link

A file: directory dependency that declares a workspace package as a peer
cannot resolve that peer under aube.

The app depends on @x/shared (workspace:*) and @x/md
(file:./modules/md), and @x/md peers on @x/shared. Pnpm records the
peer as '@x/shared': link:packages/shared in the @x/md snapshot and links
it to the workspace package, so require('@x/md') works.

Aube fails both ways:

• A frozen install from pnpm's lockfile writes
  node_modules/.aube/@x+md@file+<hash>/node_modules/@x/shared as a symlink to
  ../../../@x+shared@link+packages+shared/node_modules/@x/shared. That
  virtual-store entry is never created, so the link dangles.
• A fresh install with aube's own lockfile writes no @x/shared link in the
  @x/md copy at all.

Either way require('@x/md') fails with MODULE_NOT_FOUND. The hoisted
linker fails the same way.

The repro is a three-package local workspace with no registry dependencies.
Each install gets fresh isolated storage, and pnpm's lockfile seeds the frozen
aube case.

I found it with an Expo module in pingdotgg/t3code that is installed as
file:./modules/t3-markdown-text and peers on two workspace packages; the
mobile typecheck cannot resolve its workspace imports under aube.

Could aube link a file: dependency's workspace peers to the workspace
packages, as pnpm does?

Thanks for the clear repro. I reproduced both failures, the dangling link from pnpm's lockfile and the missing link on a fresh install, in isolated and hoisted mode. There were two causes: aube never read a file: package's peerDependencies, and it kept pnpm's link: snapshot edge as a raw string that points at a virtual-store entry that doesn't exist.

The fix is up in #1679. With it, your repro.sh passes for the pnpm control, the frozen install from pnpm's lockfile, and the fresh install. @x/md now resolves @x/shared to the workspace package.

One limit: a required peer of a file: package that nothing in scope provides is still not auto-installed. That isn't your case, since @x/shared is a direct dependency of the app.

Implemented in #1679: fix(install): link workspace peers of file: dependencies

[mwolson]

Retested with aube 2.7.0 linux-x64 (2026-10-07):

• Repo: https://github.com/mwolson/tmp-aube-issues
• Case: file-dep-workspace-peer-link

PNPM_BIN=/path/to/real/pnpm ./repro.sh

It now exits 0 with native pnpm 12.8.1 as the control. The pnpm control, the frozen install from pnpm's lockfile, and the fresh aube install all link @x/md to the workspace @x/shared.

I also checked the original case in pingdotgg/t3code: a frozen aube install links the @t3tools/shared and @t3tools/client-runtime peers of @t3tools/mobile-markdown-text to the workspace packages, and the mobile typecheck passes without the tsconfig path mapping I had been carrying.

Fix shipped in aube 2.7.0 via #1679. Marking your reply as the answer.
