How to install pyright

Pyright is a Python type checker written in TypeScript. This page carries no procedure of its own; it records what the project is and what to look at before touching it.

Distribution in practice

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

Day-to-day direction belongs to the maintainers. They set the roadmap, cut releases, and decide which platforms stay supported.

Prior checks

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

If something looks wrong

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 these notes

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

Keeping environments clean

Isolating environments, whether with a version manager or per-project directories, removes a whole category of confusing behaviour later on.
