This is why projects don't provide binary wheels for Python 3.11 until the ABI is stabilized. Unfortunately, when enabling pip's cache, this means that wheels cached for Python 3.11 alpha 2 will get used for Python 3.11 alpha 3 and are then likely to break or segfault. This is not a theoretical concern, this broke urllib3's test suite, and likely cryptography's test suite as well. See https://bugs.python.org/issue46320 for more details.\r\n\r\nWithout this change, our options are disabling pip's cache altogether or stop testing Python 3.11.\r\n\r\n**Are you willing to submit a PR?**\r\n\r\nNo, sorry.","author":{"url":"https://github.com/pquentin","@type":"Person","name":"pquentin"},"datePublished":"2022-01-12T14:39:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/319/setup-python/issues/319"}
