Hugo van Kemenade <hugovk+python@gmail.com> added the comment: I cannot reproduce this (macOS, Python 3.10, pip 22.0.4). As xtreak said, it's probably caused by using a very old version of pip (9.0.1 from Nov 6, 2016), so let's close it. Please let us know if it happens again, and whether updating pip helps. ---------- nosy: +hugovk stage: needs patch -> resolved status: open -> closed _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue36795> _______________________________________
