hitting an odd pypi/pex building error today a lot:
Copy code
ERROR: Could not find a version that satisfies the requirement pantsbuild.pants.testutil<2.15,>=2.14.0a0
ERROR: No matching distribution found for pantsbuild.pants.testutil<2.15,>=2.14.0a0
seems like there are definitely distributions that match that

I may be blind but I see 0 constraint of which Python (via --python or ICs or anything). Is
pex
installed in a venv that uses the interpreter you want? (I.E.: CPython 3.{7,8,9} - since its Pants and Pants requires those?
Oh, this is Pants log output I think. Yeah - so do you have Pants configured for this target / resolve / what have you to restrict to 3.{7,8,9} or narrower?
Is this a lock process or something else?
Basically full data always is very good for remote debug. Full command line, full output, Pants version.
IOW: Totally not odd if your Python is 3.10.

ah that's it... it's probably trying python 3.10
that is it... but is there an easy way to set the interpreter_constraints for a whole tree?
doing this for in-repo plugins that need to be py 3.9, whereas most of my code is py 3.10

something like:
Copy code
# some/tree/BUILD
__defaults__({python_sources: {"interpreter_constraints": ...}})
