Question

/home/zach/project/.venv/lib/python3.7/site-packages/poetry/version/requirements.py:170: UserWarning: warn_ungrouped_named_tokens_in_collection: setting results name 'specifier' on And expression collides with '_original_end' on contained expression
  VERSION_SPEC = originalTextFor(_VERSION_SPEC)("specifier")
/home/zach/project/.venv/lib/python3.7/site-packages/poetry/version/requirements.py:173: UserWarning: warn_ungrouped_named_tokens_in_collection: setting results name 'marker' on And expression collides with '_original_end' on contained expression
  MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")

I've been seeing the above warning messages while using poetry commands such as

poetry install
poetry run
poetry shell

I pip installed poetry 0.12.17 in my Python 3.7.0 virtual environment.

I saw this in a completely different package build

/usr/local/lib/python3.6/dist-packages/packaging/requirements.py:57: UserWarning: warn_ungrouped_named_tokens_in_collection: setting results name 'specifier' on And expression collides with '_original_end' on contained expression
  VERSION_SPEC = originalTextFor(_VERSION_SPEC)("specifier")
/usr/local/lib/python3.6/dist-packages/packaging/requirements.py:60: UserWarning: warn_ungrouped_named_tokens_in_collection: setting results name 'marker' on And expression collides with '_original_end' on contained expression
  MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")

But i'm not using poetry

Seems to be an issue with pyparsing 2.4.1, as reverting it to 2.4.0 no longer shows the warning.

[zachliu]

@amarshall Confirmed! Reverted to pyparsing==2.4.0 the warning messages disappeared. Now the question is why :thinking:

[Skufler]

Got the same issue, but there isn't pyparsing in dependencies. Here is my pyproject.toml
```
[tool.poetry.dependencies]
python = "^3.7.0"
asyncio = "^3.4"
aiohttp = "^3.4"
motor = "^2.0"
umongo = "^1.0"
pyyaml = "^3.13"

[tool.poetry.dev-dependencies]
pytest = "^3.4"
black = {version = "^18.3-alpha.0",allows-prereleases = true}
mypy = "^0.650.0"
wemake-python-styleguide = "^0.5.1"
pytest-mock = "^1.10"
pytest-asyncio = "^0.9.0"
pytest-aiohttp = "^0.3.0"

[zachliu]

@Skufler Could you double check your poetry.lock file?

[Cgironalas]

Just ran some tests, it seems like doing pip install poetry==0.12.16 installs pyparsing==2.4.1. I'd guess it installs the same version with poetry==0.12.17

[Skufler]

@zachliu
Yes, you can check by yourself
lock.txt

pyparsing 2.4.1 has been removed from pypi :laughing:

[henriklindgren]

pyparsing 2.4.1 has been removed from pypi laughing

Yeah :) 2.4.1.1 is 2.4.1, see https://github.com/pyparsing/pyparsing/releases/tag/pyparsing_2.4.1.1

Yeah :) 2.4.1.1 is 2.4.1, see https://github.com/pyparsing/pyparsing/releases/tag/pyparsing_2.4.1.1

pyparsing 2.4.1.1 still causes this warning :man_facepalming:

[ghost]

Can also confirm. Due to how my project's CI pipelines work, I am getting about thirty of these mangled with my other output each time my pipelines run :sweat_smile:

Pyparsing 2.4.2 (pushed to PyPI this evening) disables these warnings by default

[zachliu]

Pinned Pyparsing to 2.4.2 in my lock file. Everything is hunky-dory. Thank you guys.

[rzuckerm]

Pyparsing 2.4.2 is not solving this problem for me:

/usr/local/lib/python3.6/dist-packages/poetry/version/requirements.py:170: UserWarning: warn_ungrouped_named_tokens_in_collection: setting results name 'specifier' on And expression collides with '_original_end' on contained expression

What about pyparsing 2.4.0?
