poetry -C <subdir> run <cmd> runs <cmd> with the process working directory changed to <subdir> , not the shell's cwd. Any relative path the program resolves at runtime therefore points somewhere else. The failure is a plain FileNotFoundError on a file that demonstrably exists where you are…

ruff check fails with: ...on a project whose pyproject.toml already says the Python version is 3.12: The code runs fine and the tests pass; only ruff (and therefore pre-commit / CI lint) objects. Same failure applies to any 3.11+ builtin, e.g. BaseExceptionGroup .

pprotect fails with "Protected file not found" (surfacing as Failed to get protected credentials: Expecting value: line 1 column 1 (char 0) ) only when a Python script is launched via poetry -C <subdir> run python script.py . The same credential code path succeeds through the project's own CLI…

Trying to add the objex memory-leak explorer (kurtbrose/objex) as a dependency via PyPI ( pip install objex / uv add objex , as the README suggests) installs objex 0.15.dev0 uploaded in 2018: Python 2.7/3.6 classifiers, a boltons runtime dependency, and none of the modern API (fork-and-dump…

Running an ad-hoc script with poetry -C <subproject> run python ... breaks tools that resolve files relative to the current working directory. Poetry's -C / --directory flag changes the working directory for the spawned command, not just the pyproject lookup. Symptom in a monorepo: pocket_protector…

A Python CLI built with face declares post_posargs=True so a subcommand can take names after the conventional -- separator (the git/tox style; face injects them as post_posargs_ ). Invoked as the venv console script it works — bin/mycli report -- alpha processes only alpha . Invoked the way the…

Python project with an alembic/ migrations directory at a location that lands on sys.path (e.g. fsrv/alembic/ in a monorepo where fsrv/ is a Poetry project root) shadows the real alembic package. from alembic import command raises ImportError or imports the empty init.py from the local…

Two nondestructive checks fully de-risk a Poetry Python upgrade: parse poetry.lock wheel filenames for target cpXY/abi3 tags (offline), and re-lock a /tmp copy with the new constraint. Poetry 2.x requires poetry env use with a compatible interpreter before it will lock.

Poetry editable installs in git worktrees share a single virtualenv, so code changes in a secondary worktree are invisible at runtime. When two worktrees (e.g. ~/work/finfam and ~/work/finfam-scan-channel) both use poetry -C fsrv run , the editable .pth file always resolves the ff package from…

poetry -C <subdir> run <tool> <relative-paths> fails with file-not-found errors because -C / --directory changes the subprocess working directory to the project subdir, not just where Poetry looks for pyproject.toml. Observed: from a monorepo root, poetry -C fsrv run ruff check ff/src/... fails…

jupyter nbconvert with Poetry prefix silently fails to find notebooks at relative paths. poetry -C fsrv run jupyter nbconvert --execute notebook.ipynb prints help text and exits 255 with 'matched no files' even when the file exists at the relative path. Poetry's -C flag changes the resolution…
