I'm running an M1 laptop and am having trouble installing*

grpcio

when using pants. I'm trying to run some tests but I get a very long error

ERROR: Failed building wheel for grpcio
ERROR: Failed to build one or more wheels

One of the line I see before getting a whole bunch of irrelevant

c

noise is

Building requirements.pex with 4 requirements: google-cloud-pubsub~=2.14.1, google-cloud-secret-manager~=2.12.6, pydantic~=1.10.2, pytest~=7.1.3

I've set

[python]
interpreter_constraints = ["CPython==3.10"]

I'm confused because if I create a

venv

via

python3.10 -m venv venv

I can install all of the above dependencies. I've tried adding

--keep-sandboxes=on_failure

but I don't know how to inspect the sandboxes (they just seem to be bash files?)

It's not irrelevant noise. Pants has selected an arm interpreter which there is no published wheel for; so it must build one from the sdist: https://pypi.org/project/grpcio/#files I bet when you create the venv you're either using an x86_64 interpreter via Rosetta or you're using an arm interpreter there too, but there are environment variables used as part of the build that Pants blocks (Pants blocks all env vars you don't otherwise leak using https://www.pantsbuild.org/docs/reference-subprocess-environment#env_vars)

Thanks for the link
