PIP Internals
summary
Covers how pip finds and installs Python packages by querying indexes and package metadata to list candidate distributions, preferring wheel files and falling back to building source distributions (sdists) with setuptools when necessary. Describes pip’s one-by-one installation into an environment with rollback on failure, and its deterministic requirement resolution using version metadata and constraints (including METADATA, wheel files, cache and environment markers). Demonstrates concrete commands, files involved, and example workflows that succeed or fail.
