Enterprise / Air-Gapped Installation

If your environment blocks access to PyPI or GitHub, you can create a portable wheel bundle on a connected machine and transfer it to the air-gapped target.

Step 1: Build the wheel on a connected machine

Important: pip download resolves platform-specific wheels (e.g., PyYAML includes native extensions). You must run this step on a machine with the same OS and Python version as the air-gapped target. If you need to support multiple platforms, repeat this step on each target OS (Linux, macOS, Windows) and Python version.

# Clone the repository
git clone https://github.com/github/spec-kit.git
cd spec-kit

# Build the wheel
pip install build
python -m build --wheel --outdir dist/

# Download the wheel and all its runtime dependencies
pip download -d dist/ dist/specify_cli-*.whl

Step 2: Transfer the dist/ directory

Copy the entire dist/ directory (which contains the specify-cli wheel and all dependency wheels) to the target machine via USB, network share, or other approved transfer method.

Step 3: Install on the air-gapped machine

pip install --no-index --find-links=./dist specify-cli

Step 4: Initialize a project

No network access is required — bundled assets are used by default:

specify init my-project --integration copilot

Note: Python 3.11+ is required.

Windows note: Offline scaffolding requires PowerShell 7+ (pwsh), not Windows PowerShell 5.x (powershell.exe). Install from https://aka.ms/powershell.

Git Credential Manager on Linux

If you're having issues with Git authentication on Linux, you can install Git Credential Manager:

#!/usr/bin/env bash
set -e
echo "Downloading Git Credential Manager v2.6.1..."
wget https://github.com/git-ecosystem/git-credential-manager/releases/download/v2.6.1/gcm-linux_amd64.2.6.1.deb
echo "Installing Git Credential Manager..."
sudo dpkg -i gcm-linux_amd64.2.6.1.deb
echo "Configuring Git to use GCM..."
git config --global credential.helper manager
echo "Cleaning up..."
rm gcm-linux_amd64.2.6.1.deb
