anyone ever seen this error on an m1 mac (pants 2.12)?
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
  ... 724 more ...

That could be this: https://github.com/pantsbuild/pex/pull/1886 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.

lol
is there a way to get around it

I 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_wheels

uhhh ok
now I see this?:

You'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 
-vvv
to get more output or 
--log /tmp/debug.log
You may also want to add a line to echo 
$ARCHFLAGS
in there. Basically anything you can think of to debug why are these wheels not consdered compatible by the pip in that venv: https://pypi.org/project/pantsbuild.pants/#files
