Hello team 👋 I have a situation where for one particular developer on one particular machine,

pants

on v2.16 (yes, I know it's deprecated) keeps using the wrong interpreter constraints for resolves instead of what's in

pants.toml

when running

export

generate-lockfiles

. This generally results in

export

generate-lockfiles

failing. Other developers on different machines cannot replicate the issue. I've verified that the user does not have a

~/.pants.rc

file and the same error appears when using

--no-pantsrc

. If I use the

--keep-sandboxes=on_failure

parameter, once the command fails, if I remove the

--python

parameter from

__run.sh

scrip, then the script succeeds. Is there anything else I should be checking?

What python versions do people have installed? Any notable differences?

Everyone basically has an installation of 3.8 and 3.9

Can you confirm specifically what a working machine has and the failing machine has?

Everyone has 3.8.10 and 3.9.6

But I don't believe the exact python versions matter here,

pants

is using 3.8 on resolves where we specifically set

intepreter_constraints>=3.9

And on

generate-lockfiles

specifically, we get this error:

Copy code

The conflict is caused by:
     The user requested pendulum<3
     dagster 1.7.9 depends on pendulum<4 and >=3; python_version >= "3.12"

but there is no

interpreter_constraint

where we even allow python 3.12 nor is python 3.12 installed on this user's laptop

Thanks for the detail, and sorry for the trouble. Can you share your pants.toml and/or any relevant interpreter constraints? I’m not sure how you’ll best narrow this down… some ideas: • use a fresh cache by redirecting the caches to temporary dirs (https://www.pantsbuild.org/2.21/reference/global-options#local_store_dir and https://www.pantsbuild.org/2.21/reference/global-options#named_caches_dir) • compare the __run scripts in detail, especially any paths to Python interpreters • ???

Sorry, the user who is having trouble with this is a little busy this week, but I will get back to you on this thread as soon as I can
