I don’t know the details, but I did read that Poetry has a sophisticated dependency resolver.
https://github.com/sdispater/poetry I don’t know if there is a way to access the resolver independently of the tool, but perhaps it would provide a handy reference. 2018년 7월 23일 (월) 오전 5:49, Thomas Kluyver <tho...@kluyver.me.uk>님이 작성: > Hi all, > > Do we know of any tool that can, given the name of one or more packages, > follow dependency chains and produce a list of packages in the order they > need to be installed, assuming every package needed will be built from > source? > > Running "pip download --no-binary :all: ipython" gets me a set of sdists > to be installed, but I lose any information about the order.
