Hi! I'm updating a plugin to 2.13 (from 2.9) and getting this kinda.... weird error when I try to run my tests:

➜ ./pants test pants_plugins/sendwave/pants_docker/test_sources.py

    But this pex only contains:

Use `--keep-sandboxes=on_failure` to preserve the process chroot for inspection.

I think the advice is to change versions incrementally.

yeah I'm trying that now but it's a little weird to be PEX environment errors?

You also need to regenerate your lock files in each change.

I... am not using the lock files 😞 I have a constraints.txt which doesn't seem to be compatible with that I also need to make my plugin compatible with the new lockfile stuff and I'm not really sure how to do that

Can’t comment on that sorry.

@hundreds-father-404 would be a good person to lend insight into this

thanks! I am kind of speaking to myself here! but I think I know roughly the direction things need to go!

Cool! Ping if you get stuck. Someone will be happy to help you out.

just posted a (slightly) more thought out question below! 🙂
