I don't have any expectations either way. My requirements for pip are so low I barely even know what a requirements file is :-) But pip stands for "pip installs packages", not "pip manages packages". For example: - there are no rollbacks and it doesn't handle revisions; - pip uninstall is completely unaware of dependencies; https://github.com/pypa/pip/issues/3867 When pip resolves dependencies, it does it in the simplest possible way that *usually* works. It has no satisfiability solver. "No effort is made to ensure that the dependencies of all packages are fulfilled simultaneously. This can lead to environments that are broken in subtle ways, if packages installed earlier in the order have incompatible dependency versions relative to packages installed later in the order." https://www.anaconda.com/blog/understanding-conda-and-pip SageMath: "Pip is NOT a package manager. Pip is just a Python module installer, it does very little to help install non-Python dependencies, and is not very smart about version handling." https://wiki.sagemath.org/days77/packaging#Pip.2FPyPI OpenSuse: "The way pip and wheels interact with each other seems to demonstrate that pip is not a package manager but more a python module manager." https://lists.opensuse.org/archives/list/fact...@lists.opensuse.org/message/LQZTHDFTHHP2NS4RP36DUZPVM6YDW2HV/ -- Steve _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/OUNIZGPKVPH7EHRDTF47O6BESX3KXH4B/ Code of Conduct: http://python.org/psf/codeofconduct/
