Hi, sorry you had a bad experience with this. We have large numbers of users on M1 who are not encountering issues, so there may be something going on specifically with your system. I wonder if your shell is running under rosetta, or rosetta is getting involved in some way?

I've setup pants on M1 to be used among other platforms incl Linux and Intel Mac. Pantsbuild itself might not be the issue per se, but I've run into a lot of issues with science packages that have a hard dependency on scipy and numpy that are not M1 compatible for no reason.

@boundless-zebra-79556 That's interesting feedback about science packages. Would you mind opening a ticket with more details so we can track that and hopefully gather additional information from other users?

Hey guys! Thank you for responding. I am extremely impressed with Pants and have had very positive experiences with it outside of my M1 environment, so I am rooting for you! I don't think Rosetta is to blame. I tried running pants under rosetta to fix the issues, but it didn't solve my problems. It comes down to the fact that generated Pex files seem to be targetting the wrong architecture, or that necessary dependencies aren't being resolved somehow.

Trying to run a test on the library with these requirements results in the following message:
