Install

Official Installer

Alternatively, use the official installer:

curl --proto '=https' --tlsv1.2 -sSf https://download.libra.tools/install.sh | sh

macOS Prerequisites

The installer verifies the download with an Ed25519-signed manifest, which requires OpenSSL 3+ (stock macOS ships LibreSSL, which does not support Ed25519). If the installer fails at the verify stage with signature verifier unavailable, install OpenSSL via Homebrew and re-run the installer:

# Check: must report OpenSSL 3+/4+, not LibreSSL
openssl version

# If it reports LibreSSL, install OpenSSL and re-run the installer in the same shell
brew install openssl@3
which -a openssl   # /opt/homebrew/bin/openssl should come first

[!WARNING] Do not use LIBRA_ALLOW_FALLBACK=1 as the workaround — it skips Ed25519 signature verification entirely.

Homebrew

Install Libra with Homebrew on macOS or Linux:

brew tap libra-tools/libra
brew install libra

Verify

Verify the installation:

libra --version
libra --help

If you prefer to review the installer before running it:

curl -fsSL https://download.libra.tools/install.sh
