Installing Dojo

Dojo's installation process was designed to be idiomatically consistent with its dependencies, Rust and Cairo. You can get up-and-running in just a few steps, and be building provable games in no time.

Quick Start

For existing Cairo developers, the fastest way to get started is with asdf:

# Install the asdf plugins
asdf plugin add sozo https://github.com/dojoengine/asdf-sozo.git
asdf plugin add katana https://github.com/dojoengine/asdf-katana.git
asdf plugin add torii https://github.com/dojoengine/asdf-torii.git
 
# Install the Dojo toolchain
asdf install sozo latest
asdf install katana latest
asdf install torii latest

This will install all necessary dependencies and tools. Skip to Verification to test your installation.

Detailed Installation

System Requirements

Before installing Dojo, ensure your system meets these requirements:

• Operating System: macOS, Linux, or Windows with WSL2
• Memory: At least 4GB RAM (8GB recommended)
• Storage: 2GB free disk space for toolchains and dependencies
• Network: Stable internet connection for downloading binaries
• Dependencies: curl, jq, and git (usually pre-installed on most systems)

Prerequisites

Before installing Dojo, you'll need these foundational tools:

1. Install Rust with rustup

Rust is required for Dojo's infrastructure tools (Katana and Torii).

Minimum version: 1.85.0

curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh

This installs Rust's executables, including the cargo package manager, in the ~/.cargo directory.

cargo --version
# Should output: cargo 1.85.0 (or later)

For more information, see the Rust installation guide.

2. Install Cairo with starkup

Dojo is written in Cairo, StarkWare's language for creating provable programs.

Minimum version: 2.10.1

curl --proto '=https' --tlsv1.2 -sSf https://sh.starkup.sh | sh

This installs Cairo's toolchain, including the scarb package manager and build tool, in the ~/.asdf directory.

Note: asdf does not automatically add itself to your path. Consider appending ~/.asdf/shims to your terminal's $PATH variable to simplify development.

scarb --version
# Should output: scarb 2.10.1 (or later)

For more information, see the starkup documentation.

Installing Dojo

The Dojo framework consists of a Cairo framework and three Rust-based tools: katana, torii, and sozo.

Installing with asdf

asdf is currently the preferred way to install Dojo. asdf is a popular version manager, enabling easy programmatic installation of dependencies through the .tool-versions file.

asdf plugin add katana https://github.com/dojoengine/asdf-katana.git
asdf plugin add torii https://github.com/dojoengine/asdf-torii.git
asdf plugin add sozo https://github.com/dojoengine/asdf-sozo.git

# Install the latest version
asdf install {sozo,katana,torii} latest
 
# Install specific versions
asdf install {sozo,katana,torii} 1.6.0
 
# List available versions
asdf list all {sozo,katana,torii}

# Set version locally (in project .tool-versions)
asdf set {sozo,katana,torii} latest
 
# Set version globally (in user home .tool-versions)
asdf set --home {sozo,katana,torii} latest

Installing with dojoup

dojoup is an alternative way to install and manage Dojo installations. Dojoup is version-aware and will automatically install compatible versions of katana, torii, and sozo.

curl -L https://install.dojoengine.org | bash

dojoup install

# Install a specific version
dojoup install 1.6.0
 
# Get help
dojoup --help

Verification

After installation, verify that all tools are working correctly:

Check Dojo Tools

# Check Sozo (CLI tool)
sozo --version
# Should output: sozo 1.6.0 (or later)
 
# Check Katana (sequencer)
katana --version
# Should output: katana 1.6.0 (or later)
 
# Check Torii (indexer)
torii --version
# Should output: torii 1.6.0 (or later)

Test Your Installation

Create a simple test project to verify everything works:

# Clone the dojo-starter repository
git clone https://github.com/dojoengine/dojo-starter
 
# Navigate to the project
cd dojo-starter
 
# Build the project
sozo build
 
# Test successful if no errors appear

Troubleshooting

Common Installation Issues

dojoup: command not found

Problem: After installing dojoup, the command is not found.

Solution:

1. Restart your terminal completely
2. If still not working, manually source the environment: source ~/.dojo/env
3. Check that ~/.dojo/bin is in your PATH: echo $PATH | grep -o ~/.dojo

starkup installation fails

Problem: starkup fails to install or configure properly.

Solution:

1. Ensure asdf is properly installed
2. Add ~/.asdf/shims to your PATH: export PATH="$HOME/.asdf/shims:$PATH"
3. Or, add it via your shell profile (.bashrc, .zshrc, etc.)

Version compatibility issues

Problem: Incompatible versions between Rust, Cairo, or Dojo components.

Solution:

1. Check current versions:

   cargo --version    # Should be 1.85.0+
   scarb --version    # Should be 2.10.1+
   sozo --version     # Should be 1.6.0+

2. Update if needed:

   rustup update              # Update Rust
   asdf install scarb latest  # Update Cairo/Scarb
   dojoup install             # Update Dojo

Build failures in test project

Problem: sozo build fails in the test project.

Solution:

1. Ensure all dependencies are installed

2. Try cleaning and rebuilding: sozo clean && sozo build

3. Check for version mismatches between your installed tools
