01 / INSTALL

One command.

The installer resolves the current packaged compiler release from GitHub, uses published SHA-256 metadata when available, and adds the uv command to your PATH.

Linux x86_64 / macOS (Apple Silicon)

$curl -fsSL https://ultraviolet-lang.org/install | sh

Windows x86_64

$powershell -c "irm https://ultraviolet-lang.org/install.ps1 | iex"

Already using Python's uv? The installer detects the conflict and asks: it can keep the existing tool available as pyuv, or install Ultraviolet's CLI as uvc instead.
