Python Pip 20.3 Released with new resolver
Your package manager should be boring, extremely backward and forward compatible, and never broken.  Experience has shown this not to be true for python.  Several times over the years i’ve found myself, pinning, upgrading, downgrading, or otherwise juggling versions of setuptools and pip in order to work around some bug. Historically I have had far more problems with the machinery to install python packages I have had with all of the other python packages being installed combined, and that is absurd.
