bug: poetry is using default python version instead of venv python as result of new version in virtualenv v20.33.0 #10490
Description
Description
poetry is using the wrong python version when running in github action. it uses the machine default version instead of the venv python version.
Using virtualenv: /home/runner/.cache/pypoetry/virtualenvs/lb-kafka-C-kvVqEG-py3.13
....
error:
Current Python version (3.12.3) is not allowed by the project (~=3.13).
Please change python executable via the "env use" command.
Error: Process completed with exit code 1.
Workarounds
locking virtualenv==20.32.0 when installing poetry using constraints.txt as pip args fixes the issue.
