@lowitea any chance we can add a test case for this somewhere?

[lowitea]

@abn i couldn't think of how to do it :(

@abn Hi
Is it possible to take this without tests?

[abn]

Looks like the solution is not being displayed (this bit).

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For black, a possible solution would be to set the `python` property to ">=3.6,<4.0"

    https://python-poetry.org/docs/dependency-specification/#using-environment-markers

Test Command

podman run --rm -i --entrypoint bash python:3.8 <<EOF
set -xe
python -m pip install -q git+https://github.com/python-poetry/poetry.git@refs/pull/3111/head
install -d foobar
cat > pyproject.toml <<TOML
[tool.poetry]
name = "foobar"
version = "0.1.0"
description = ""
authors = ["Your Name <[email protected]>"]

[tool.poetry.dependencies]
python = "^3.5"

[tool.poetry.dev-dependencies]

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"
TOML
poetry add black
EOF

Using version ^20.8b1 for black

Updating dependencies
Resolving dependencies...
The current project's Python requirement (>=3.5,<4.0) is not compatible with some of the required packages Python requirement:
  - black requires Python >=3.6, so it will not be satisfied for Python >=3.5,<3.6

Because no versions of black match >20.8b1,<21.0
 and black (20.8b1) requires Python >=3.6, black is forbidden.
So, because foobar depends on black (^20.8b1), version solving failed.

Let me check. I’ll contact you later.

Closing this as we've removed the default tracebacks with a Cleo change.
