mmm yeah when we ran into the similar case on windows i was thinking one like this might also exist - where a package in a dep imports a package in the current project. i don't have an explicit test case for it (obviously), but assuming the issue is what i think it is, the fix is straightforward.

[jessfraz]

this is related to #114

[jessfraz]

same error: https://gist.github.com/69b30f0d8531f3d0273f46a48d503f3c

[sdboyer]

yep, OK. i'm pretty sure i know exactly what this is. if i do, then both the fix and a test case for it should be easy.

[jessfraz]

Ah yeah it's a cyclic import

[sdboyer]

but just project-level cyclic, not package-level, right?

[jessfraz]

Yeah just swarm imports some subpackages in docker
