poetry 1.7.0 poetry init fails with "Poetry could not find a pyproject.toml ..."

[danielhoherd]

• Poetry version: Poetry (version 1.7.0)

• Python version: Python 3.11.6 (main, Nov 1 2023, 10:08:51) [GCC 12.2.0]

• OS version and name: Debian 12, macOS 14.1

• pyproject.toml: N/A, file was never created by poetry init

• I am on the latest stable Poetry version, installed using a recommended method.

• I have searched the issues of this repo and believe that this is not a duplicate.

• I have consulted the FAQ and blog for any relevant entries or release notes.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

Running poetry init with poetry 1.7.0 and then interactively adding dependencies causes an error. The error is not seen if you skip adding dependencies.

$ docker run --rm -ti python:3.11 /bin/sh
# pip install poetry >/dev/null 2>&1
# poetry --version
Poetry (version 1.7.0)
# mkdir test
# cd test
# poetry init -vvv

This command will guide you through creating your pyproject.toml config.

Confirming, interactive dependencies are busted when creating a new project.

Am also running into this - I guess the solution is to pin 1.6.1 for now

[finswimmer]

Hey,

thanks for reporting.

This one is a bit strange. I can reproduce it within a docker container, but not on my "normal" system.

Also a RuntimeError is thrown. But how you can see in the stacktrace, this is an expected usecase which should be catched and handled.

@Secrus any chance this has something to do with cleo?

[dimbleby]

I think it's a regression from #8559, which now tries to get hold of the poetry configuration before the poetry object exists.

(untested theory, but it sounds plausible)

[danielhoherd]

@duncanariey alternatively if you touch pyproject.toml in shell or open('pyproject.toml', 'a').close() in python it will work in 1.7.0.
