Python packaging must be getting better – a datapoint (via) Luke Plant reports on a recent project he developed on Linux using a requirements.txt file and some complex binary dependencies—Qt5 and VTK—and when he tried to run it on Windows… it worked! No modifications required.
I think Python’s packaging system has never been more effective… provided you know how to use it. The learning curve is still too high, which I think accounts for the bulk of complaints about it today.
