Problem

Jupyverse is a Python mono-repo consisting of a "main" jupyverse package and a bunch of "sub-packages" in plugins (fps-contents, fps-kernels, etc.).
When releasing e.g. 0.1.0, I would like jupyverse to depend on sub-packages with version ==0.1.0 too. But I cannot pin them in setup.cfg, because at the time of release these sub-packages would not have been released yet.
Maybe I'm missing something?
