Hey, I think I've discovered a bug! We have a pip dependency in a requirements.txt that has a >= for it's version, and newer versions don't support our (old) version of Python (3.5). It appears Pants is struggling to resolve the proper version supported by the selected python interpreter

Hey Noah, sorry you're having this issue. Can you say what the requirement is, and post the error you're getting?

The error is that the module can't get imported at runtime for tests (or if you drop into a repl or something). The requirement is pandas>=0.23.4
