Installation

There are six main ways to install medusa:

  1. Using Go Install
  2. Using Homebrew
  3. Using Nix
  4. Using Docker
  5. Building from source
  6. Using Precompiled binaries

If you have any difficulty with installing medusa, please open an issue on GitHub.

Installing with Go Install

Prerequisites

You need to have Go installed (version 1.20 or later). Installation instructions for Go can be found here.

Install medusa

Run the following command to install the latest version of medusa:

go install github.com/crytic/medusa@latest

This will download, compile, and install the medusa binary to your $GOPATH/bin directory. Make sure this directory is in your PATH environment variable.

Installing with Homebrew

Note that using Homebrew is only viable (and recommended) for macOS and Linux users. For Windows users, you must use one of the other installation methods.

Prerequisites

Installation instructions for Homebrew can be found here.

Install medusa

Run the following command to install the latest stable release of medusa:

brew install medusa

To install the latest development version:

brew install --HEAD medusa

Installing with Nix

Prerequisites

Make sure nix is installed and that nix-command and flake features are enabled. The Determinate Systems nix-installer will automatically enable these features and is the recommended approach. If nix is already installed without these features enabled, run the following commands:

mkdir -p ~/.config/nix
echo 'experimental-features = nix-command flakes' > ~/.config/nix/nix.conf

Build medusa

To build medusa with nix:

# Clone the repository if you haven't already
git clone https://github.com/crytic/medusa
cd medusa

# Build medusa
nix build

The resulting binary can be found at ./result/bin/medusa.

Install medusa

After building, you can add the build result to your PATH using nix profiles by running the following command:

nix profile install ./result

Installing with Docker

Prerequisites

You need to have Docker installed. Installation instructions for Docker can be found here.

Using the Docker image

Pull the latest Docker image:

docker pull crytic/medusa

Run medusa in a container:

docker run -it --rm -v $(pwd):/src crytic/medusa <command>

This will mount your current directory to /src in the container and run the specified medusa command.

Building from source

Prerequisites

Before building medusa from source, you will need:

Build medusa

Run the following commands to build medusa (this should work on all OSes):

# Clone the repository
git clone https://github.com/crytic/medusa

# Build medusa
cd medusa
go build -trimpath

You will now need to move the binary (medusa or medusa.exe) to somewhere in your PATH environment variable so that it is accessible via the command line. Please review the instructions here (if you are a Windows user, we recommend using the Windows GUI).

Precompiled binaries

The precompiled binaries can be downloaded on medusa's GitHub releases page.

NOTE: macOS may set the quarantine extended attribute on the downloaded zip file. To remove this attribute, run the following command: sudo xattr -rd com.apple.quarantine <my_file.tar.gz>.

Once downloaded, you will need to unzip the file and move the binary to somewhere in your $PATH. Please review the instructions here (if you are a Windows user, we recommend using the Windows GUI).
