my project recently upgraded to 2.25, but when i try to run pants i see:

Failed to fetch <https://github.com/pantsbuild/pants/releases/download/release_2.25.0/pants.2.25.0-cp39-darwin_x86_64.pex>

2.25 switches the internal python version from python3.9 to python3.11. I suspect either: • you are using an out-of-date

pants

launcher binary, or • you have some in-repo pants-plugins. So, you will need to update your interpreter_constraints to use 3.11 instead of 3.9 in the resolve used for your pants-plugins. https://github.com/pantsbuild/pants/blob/2.25.x/docs/notes/2.25.x.md#internal-python-upgrade

the answer was right in front of me the whole time:

<default> (when SCIE_BOOT is not set in the environment)  Detects the current Pants installation and launches it.
bootstrap-tools                                           Introspection tools for the Pants bootstrap process.
update                                                    Update scie-pants.

updating the launcher binary fixed it
