Overview

GitHub Copilot CLI requires PowerShell 7 or higher on Windows and Node.js 22 or higher when installed via npm. The official README lists Node 18 as the minimum, but the npm package install path requires Node 22+. Install Node 22+ to satisfy both. After these prerequisites are in place, install the copilot CLI itself via winget, or fall back to the npm global install if winget is unavailable on your machine.

Learning objectives

• Verify that PowerShell 7+ is your active shell.
• Install Node.js 22+ via winget and confirm the version.
• Install GitHub Copilot CLI via winget (or npm fallback) and run copilot --version.

Exercise 1.1 — Verify PowerShell 7+

1. Open PowerShell 7+ (search for “PowerShell” in the Start menu and pick the non-Windows-PowerShell entry, or run pwsh from any terminal).

2. Check the version:

    $PSVersionTable.PSVersion
   

3. Confirm the Major column reports 7 or higher. If it reports 5, you are in Windows PowerShell 5.1, which GitHub Copilot CLI does not support — install PowerShell 7 from the Microsoft Store or winget install Microsoft.PowerShell first.

Exercise 1.2 — Install Node.js 22+

1. In your PowerShell 7+ session, install the Node.js LTS:

    winget install OpenJS.NodeJS.LTS
   

2. Close and re-open the terminal so the updated PATH is loaded.

3. Confirm the version is v22.x or higher:

    node --version
   

Exercise 1.3 — Install GitHub Copilot CLI

1. Preferred path — install via winget:

    winget install GitHub.Copilot
    copilot --version
   

2. Fallback path — if winget is not available on your machine, install via npm after Lab 01 Exercise 1.2 succeeds:

    npm install -g @github/copilot
    copilot --version
   

3. Confirm copilot --version prints a version string without errors.

Verification Checkpoint

Before proceeding, verify:

• $PSVersionTable.PSVersion reports a Major of 7 or higher.
• node --version reports v22.x or higher.
• copilot --version prints a version string without errors.

Next Steps

Proceed to Lab 02 — Install the Copilot Studio VS Code extension.
