If not, that could indicate you need to tweak the “source roots” configuration: https://www.pantsbuild.org/docs/source-roots

I'd love to have a python error message like "your import does not make sense, it is not included in these 28 paths you could use here (based on your repositories BUILD files): all 28 possible imports.."

ah i think I fixed it.. in one of the parents folders above the to-be-imported library there was no BUILD file. at least it works now after moving the library to the toplevel folder. a little bit weird though

I'll try to drill down later why it didn't work.. i was just curious whether i am missing some command how to debug import errors. since dependency management in a python monorepo seems to be a major usecase of pants, i was expecting to see some helper command or debug switch to easily see some context on a particular import error.
