How one can Entry Gemini CLI?

Earlier than continuing with the set up, be sure that the system necessities are glad, and undergo the issues to bear in mind earlier than set up.

System Necessities

NodeJS is a standard prerequisite for each the CLIs. You’ll be able to set up Node.js by following the directions on its official web page from NodeJS.

Issues to Preserve in Thoughts

Previous to starting the set up of Gemini 3 Professional utilizing the command line interface (CLI), it is best to guarantee you’ve gotten put in the next prerequisite software program in your pc’s working system. First, you have to set up Node.js and npm (or yarn), and each software program have to be in your pc’s system PATH. For the Gemini CLI, you have to Node.js 18 or a later model.

Your CLI should be authenticated both by an API key or by logging in by way of your Google account. On Home windows, it’s common for customers to want to run CLI instruments by way of WSL2 to have higher compatibility and a extra Unix-like surroundings.

It is usually essential to make sure you set your working listing to the undertaking folder when working the CLI instructions for Gemini, in order that the CLI can learn or write appropriately to the undertaking for undertaking information and context.

Set up Steps

1. Examine Conditions:

• Be certain that to have at the very least Node.js 18+.
• Set up a package deal supervisor, like npm or yarn.
• Be sure you have a working terminal/command-line (PowerShell, Terminal, WSL, and many others). To put in globally:

npm set up -g @google/gemini-cli

2. Authenticate with Gemini CLI utilizing:

gemini auth login 

3. Authenticate Gemini CLI

Run:

gemini auth login

Now this command will open a brand new browser window, after which you must log in along with your Google account. Alternatively, when you’ve got a Gemini API key, you need to use that too.

export GEMINI_API_KEY="YOUR_API_KEY"

Working our CLI Cases

After finishing the set up and authentication processes, customers will instantly start to make the most of Gemini 3 Professional’s agent capabilities.

For easy inquiries, code snippets, and debugging help, use:

gemini ask "Clarify why this regex is not matching and suggest a repair." 

Utilising this Mode will set off Lengthy Contextual Reasoning, as an example, over the person’s native listing, will present:

• Parsing of the Undertaking Listing, i.e., Parse File Tree
• Studying of the Undertaking Listing Recordsdata (with acceptable permissions)
• The Capacity to Counsel and Create “patches.”
• The Capacity to Keep and Retain Reasoning Throughout A number of Instructions.
