Background

Before each breeze start-airflow, compile_provider_assets.py runs pnpm install --frozen-lockfile in each provider's plugin UI directory, for example providers/common/ai/.../plugins/www. Then it builds the UI.

pnpm records the store location that was used to install node_modules. If the current store location is different, pnpm must remove node_modules and install again. It asks for confirmation before it removes anything.

Before #73538, our lint hooks wrote store-dir=.pnpm-store into the global pnpm config. An older node_modules on a dev machine can still use that per-directory store. I removed that line from my config, so my next install used a different store.

Why

The script captures the pnpm output, so nobody sees the question. If stdin is closed, pnpm exits 0 and installs nothing. If stdin is open, pnpm waits forever.

The build then fails on each dependency that was added after the old install. For common.ai, #74334 added react-icons, and the build fails with Rolldown failed to resolve import "react-icons/lu".

What

Pass --config.confirmModulesPurge=false to pnpm install. pnpm then removes node_modules and installs again without a question. The other prek hooks that install UI dependencies on the host already pass this flag: compile_ui_assets.py, compile_ui_assets_dev.py and the ts_compile_lint_*.py hooks.

I reproduced the problem with real pnpm. I used a node_modules from before #74334, installed with a different store. On main the build fails with the error above. On this branch it builds.

How to reproduce

You may not see this problem on your machine. If pnpm config get store-dir prints .pnpm-store, every install uses the same store. Then pnpm never asks. These commands create the old install with a different store and do not change your config:

cd providers/common/ai/src/airflow/providers/common/ai/plugins/www
rm -rf node_modules dist
git checkout d8efc66ea76^ -- package.json pnpm-lock.yaml
pnpm install --frozen-lockfile --config.store-dir=/tmp/other-pnpm-store
git checkout HEAD -- package.json pnpm-lock.yaml
cd -
uv run --project scripts python scripts/ci/prek/compile_provider_assets.py ai </dev/null
