How to install py-spy

Py-spy is developer utility. This page carries no procedure of its own; it records what the project is and what to look at before touching it.

How it reaches a system

In practice this means one of a handful of routes: an operating system package index, a registry tied to a language, a version manager, or a source tree built with the project's own tooling. Which one applies is decided by the platform and by the maintainers.

Who is behind it

The project is self-governed. Whoever maintains it chooses what ships and when, and writes the accompanying material.

Prior checks

Start from the support matrix. It narrows over time, and assumptions made years ago often no longer hold.

Making sense of the result

Most unexpected behaviour traces back to resolution rather than to the project. An older copy sitting earlier in the path, or a version manager pointing somewhere else, will do it every time.

About this site

Only text is published from this domain. Each project remains exactly where its authors put it.

On reading release notes

Release notes are the cheapest way to catch a breaking change before it surprises you. They usually list platform shifts and removed defaults in the first few lines.
