Install

Lexa ships as a single native binary. Pick the path that matches your platform.

macOS / Linux

curl -fsSL https://raw.githubusercontent.com/anvia-hq/lexa/main/install.sh | sh

Windows (PowerShell)

irm https://raw.githubusercontent.com/anvia-hq/lexa/main/install.ps1 | iex

Pin a specific version

Pass the version you want to the installer:

curl -fsSL https://raw.githubusercontent.com/anvia-hq/lexa/main/install.sh | sh -s -- v0.5.1

Install from source

If you have a Rust toolchain:

cargo install --path .

Or build without installing and run from the working tree:

cargo build --release
./target/release/lexa --help

Upgrading an existing install

The lexa upgrade command replaces the running binary in place.

lexa upgrade              # latest release
lexa upgrade v0.5.1       # specific version
lexa upgrade --install-dir "$HOME/.local/bin"

By default, lexa upgrade updates the binary in the directory that contains the currently running lexa. Override that with --install-dir or the LEXA_INSTALL_DIR environment variable.

After upgrading, refresh the project graph so it picks up any new metadata:

lexa index .

Disabling the version check

lexa --version does a short cached GitHub release check to report whether lexa upgrade is available. Set LEXA_NO_UPDATE_CHECK=1 to skip it:

LEXA_NO_UPDATE_CHECK=1 lexa --version
