Gemini CLI

This repository contains the Gemini CLI tool.

Quickstart

1. Install Node 18+
2. Set your API key: export GEMINI_API_KEY="YOUR_API_KEY" (Get an API key)

• For future sessions you can add this to your shell's configuration file, or use a .env file in your project's hierarchy

3. Run with: npx https://github.com/google-gemini/gemini-cli#early-access
4. Enjoy

Examples

Once the CLI is running, you can start interacting with Gemini. Try a simple query:

> How can I build a web app?

Or ask it to perform a task using its tools:

> List files in the current directory.

API Key Setup

The Gemini CLI requires a Gemini API Key. It supports several ways to authenticate with Google's AI services. You'll need to configure one of the following methods:

1. Gemini API Key:

   • Obtain your API key from Google AI Studio: https://aistudio.google.com/app/apikey
   • Set the GEMINI_API_KEY environment variable. You can do this temporarily in your current shell session:

     export GEMINI_API_KEY="YOUR_GEMINI_API_KEY"

     Or add it to your .env file (in project directory or user home) or shell's configuration file (like ~/.bashrc, ~/.zshrc, or ~/.profile) for persistence:

     echo 'export GEMINI_API_KEY="YOUR_GEMINI_API_KEY"' >> ~/.bashrc # Or your preferred shell config file
     source ~/.bashrc # Reload the config

     Replace "YOUR_GEMINI_API_KEY" with your actual key.

2. Google API Key (Vertex AI Express Mode):

   • This key can be a general Google Cloud API key enabled for the Gemini API or Vertex AI.
   • Set the GOOGLE_API_KEY and GOOGLE_GENAI_USE_VERTEXAI environment variables:

     export GOOGLE_API_KEY="YOUR_GOOGLE_API_KEY"
     export GOOGLE_GENAI_USE_VERTEXAI=true

3. Vertex AI (Project and Location):

   • Ensure you have a Google Cloud Project and have enabled the Vertex AI API.
   • Set up Application Default Credentials (ADC). For more details, refer to the official Google Cloud ADC documentation:

     gcloud auth application-default login

   • Set the GOOGLE_CLOUD_PROJECT, GOOGLE_CLOUD_LOCATION, and GOOGLE_GENAI_USE_VERTEXAI environment variables:

     export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"
     export GOOGLE_CLOUD_LOCATION="YOUR_PROJECT_LOCATION" # e.g., us-central1
     export GOOGLE_GENAI_USE_VERTEXAI=true
