# Installation

## Requirements

- **Linux or macOS** — pyodide-build works best on Linux and macOS. Windows is not supported.
- **Python 3.12 or later** — **must** match the Python version targeted by the Pyodide cross-build environment you install.
- **Node.js** — required for testing with [`pyodide venv`](testing.md). Not needed for building. Node.js >= 24 is recommended.
