How to Install Gemini CLI

Learn how to install and configure the Gemini CLI on your system with this step-by-step guide covering prerequisites, installation, and verification.

1. 1

   Check Prerequisites

   Ensure you have Node.js 18 or later installed on your system. Open a terminal and run 'node --version' to verify. You also need npm or yarn as your package manager.

2. 2

   Install Gemini CLI Globally

   Run 'npm install -g @google/gemini-cli' in your terminal. This installs the Gemini CLI globally so you can access it from any directory on your system.

3. 3

   Authenticate with Your API Key

   Run 'gemini auth login' and follow the prompts to authenticate. You can also set the GEMINI_API_KEY environment variable directly if you prefer non-interactive setup.

4. 4

   Verify the Installation

   Run 'gemini --version' to confirm the CLI is installed correctly. You should see the version number printed to the console.

5. 5

   Configure Your Workspace

   Navigate to your project directory and run 'gemini init' to create a local configuration file. This sets up project-specific settings and preferences.
