pypiWhy Yanking a PyPI Release Is Safer Than Deleting It
When a PyPI wheel breaks, deleting it can break pins. Yanking keeps the file but tells pip to skip it for new installs. Learn how to yank with twine, verify pip’s resolver, and understand the trade‑offs.
Diagnosing pip "No matching distribution found" Errors from PyPI
When pip cannot find a version to install, the resolver has rejected every candidate on the index. This guide walks through ordered checks to find whether the cause is a name typo, interpreter mismatch, platform tag gap, or index misconfiguration.
Using PyPI’s requires‑python Field to Prevent Installation Failures
Declare the <code>requires‑python</code> field in your PyPI package to let pip reject old Python versions before installation. Learn how to set it up, test it in CI, and avoid common pitfalls.
Diagnosing and Fixing PyPI Dependency Conflicts with pip
When pip throws a ResolutionImpossible error, you’re facing a dependency conflict. This guide walks through the common causes, a quick diagnostic checklist, step‑by‑step fixes, and when to seek help. Use dry‑run, pip check, and virtual environments to keep your projects stable.

PyPI JSON API ↔ pip Client: Coordinating Per-Connection Timeouts with Total Operation Deadlines During Multi-Package Resolution
Interoperability Gap PyPI's repository APIs (both the legacy JSON endpoint at /pypi/<name>/json and the PEP 691 JSON-based simple index) impose no server-side request deadlines. The pip client enforces its own --timeout (default 15 seconds) per connection attempt and --retries (default 5) for transient failures, but these parameters apply to individual
