Hi Pants! Trying to get Pants
v2.9.0.dev1
working on an M1 macbook. We’re on Python 3.8 (we can’t upgrade to Python 3.9 just yet) and have installed Python using the homebrew /
pyenv
using x86_64 arch emulation. We’re using the Pants
docker
plugin and are stumped by the attached error. Does anyone have any insight into this? Thanks in advance!

Use --no-process-execution-local-cleanup to preserve process chroots for inspection.

I suggest trying the latest rc for 2.9.0 just released today: https://pantsbuild.slack.com/archives/C18RRR4JK/p1641423160055400

Hmmm @curved-television-6568 any insight?
Are there also native Pythons installed on your system? What does your
pants.toml
do to restrict the selected interpreters? And how are you running Pants itself?

On the phone now, but seems like it complains about the dockerfile parser lib being for the wrong platform.. if that is a hint for anyone?
Will take a closer look once I'm n front of my 💻
What version of Mac OS are you using? Edit: perhaps not as relevant, posted that before I noticed you mentioned the x86_64 emulation thing..
It seems that the arch emulation for x86_64 you are using trips up here.. as you seem to be getting the
dockerfile
lib for x86_64, but it requires the
arm64
version to work for you?
Given this import error:
Copy code
ImportError: dlopen(/Users/thoyt/.cache/pants/named_caches/pex_root/venvs/s/97bd2daa/venv/lib/python3.8/site-packages/dockerfile.abi3.so, 0x0002): tried: '/Users/thoyt/.cache/pants/named_caches/pex_root/venvs/s/97bd2daa/venv/lib/python3.8/site-packages/dockerfile.abi3.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/local/lib/dockerfile.abi3.so' (no such file), '/usr/lib/dockerfile.abi3.so' (no such file), '/Users/thoyt/.cache/pants/named_caches/pex_root/venvs/5f8edf4d6068dd9c5ff01b0865815af301a9e9d5/05ad48543d1b4172329a34b21ccc64fa30998340/lib/python3.8/site-packages/dockerfile.abi3.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/local/lib/dockerfile.abi3.so' (no such file), '/usr/lib/dockerfile.abi3.so' (no such file)
Perhaps it would be worth while to find a setup that gets this package: https://pypi.org/project/dockerfile/#files to work with a version of python on your machine, and once that works, see if you can get Pants to use the same setup.

Thanks for the links and guidance – seems promising. I’ll explore these and loop back

I am not encountering the problem with the
2.9.0rc3
version. Thanks so much and I'll be sure to report back if I encounter any other issues 🙏
