likely not a problem with poetry but with pyyaml (6.0) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 \"pyyaml (==6.0)\"'.\r\n\r\n  - Installing six (1.16.0)\r\n  - Installing snowballstemmer (2.2.0)\r\n  - Installing stevedore (3.5.0)\r\n  - Installing urllib3 (1.26.9)\r\n```\r\n\r\n## System info\r\n\r\nWSL2, Windows 11\r\n\r\n```\r\n└➜ uname -a\r\nLinux 5.15.153.1-microsoft-standard-WSL2 #1 SMP Fri Mar 29 23:14:13 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux\r\n\r\n└➜ python --version\r\nPython 3.12.3\r\n\r\n└➜ poetry --version\r\nPoetry (version 1.8.5)\r\n```\r\n\r\nI suppose the problem is related to the fact that `poetry.lock`  requires `pyyaml == 6.0`, but looks like there is a problem to build `pyyaml \u003c 6.0.1` for python 3.11 and newer (https://github.com/yaml/pyyaml/issues/736).\r\n\r\n## Proposed solution\r\n\r\n1. Maybe bump `pyyaml` dependency to the latest `6.0.2`?\r\n2. Update `poetry.lock` for python 3.12 and newer (for pyyaml package wheels are listed for 3.11 and older)","author":{"url":"https://github.com/ivanovmg","@type":"Person","name":"ivanovmg"},"datePublished":"2024-12-12T17:02:42.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/492/classes/issues/492"}
