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?

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?

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 🙏
