Installation

This guide will help you install Arc on your system.

Prerequisites

  • Python 3.12 or higher (Python 3.13 is also supported)
  • uv - Fast Python package manager (we'll install this if you don't have it)

Installing uv

Arc uses uv for dependency management. If you don't have uv installed:

# On macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# On Windows
powershell -c "irm https://astral.sh/uv/install.sh | iex"

Installing Arc

Install the latest stable release from PyPI:

pip install nl-arc

Note: The package is named nl-arc on PyPI (to avoid naming conflicts), but the command you run is still arc.

Option 2: Install from Source (Development)

Clone the repository and install in editable mode:

# Clone the repository
git clone https://github.com/non-linear-ai/arc
cd arc

# Install dependencies
uv sync

# Install with development dependencies (for contributors)
uv sync --dev

Verifying Installation

Verify Arc is installed correctly:

# Check version
arc --help

# Should display Arc's help message with available commands

You should see output showing Arc's available commands and options.

Next Steps

Now that Arc is installed, continue to:
