uv: Ultimate Victory over Installation and Dependency Chaos
summary
A single tool claims to replace pip, virtualenv and poetry-style workflows and does concrete things: one-liner install that needs no admin rights and can self-update; automatic Python download and ephemeral venvs with hardlinks so running a numpy script or launching IPython pulls packages on demand without manual activation; a script workflow and uvx for ephemeral utilities (example: TLDR, cows, polars demo) and project commands like uv lock upgrade / uv sync and uv tree outdated to list and upgrade dependencies.
