Copy code
No interpreter compatible with the requested constraints was found:
A distribution for lxml could not be resolved for /Users/ashu/.pyenv/versions/3.9.10/bin/python3.9.
Found 1 distribution for lxml that do not apply:
1.) The wheel tags for lxml 4.9.1 are cp39-cp39-macosx_12_0_arm64 which do not match the supported tags of /Users/ashu/.pyenv/versions/3.9.10/bin/python3.9:
cp39-cp39-macosx_10_16_arm64

Hard to tell. I don't have a Mac and remotely debugged a similar error just today for Python 2.7.
If that is it, I can assure you I swore more in the last 4 hours than you probably have in the last year.

08/23/2022, 2:31 AMI can't think of one besides finding all instances of 3.9 Pythons and ensuring just 1 of them is visible to Pants. The bug I pointed to I think can only happen if you have more than one interpreter of a given major.minor version (on macOS and more complex conditions after that ...).
After doing that you'd need to
rm -rf ~/.cache/pants/named_caches/pex_root/built_wheelsc

08/23/2022, 4:55 PMYou'll need to get your hands dirty here. That is pip failing to find a compatible pants. That line is here: https://github.com/pantsbuild/setup/blob/eb887ad5fd80766214e8c38102a5bc92d1342beb/pants#L376
Perhaps add
