How one can Entry Gemini CLI?

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

System Necessities

NodeJS is a typical 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), you must guarantee you might have put in the next prerequisite software program to your laptop’s working system. First, it’s essential to set up Node.js and npm (or yarn), and each software program have to be in your laptop’s system PATH. For the Gemini CLI, you will want Node.js 18 or a later model.

Your CLI should be authenticated both by an API key or by logging in through your Google account. On Home windows, it is not uncommon for customers to want to run CLI instruments through WSL2 to have higher compatibility and a extra Unix-like surroundings.

It’s also vital to make sure you set your working listing to the venture folder when working the CLI instructions for Gemini, in order that the CLI can learn or write accurately to the venture for venture recordsdata and context.

Set up Steps

1. Verify Conditions:

• Make certain to have at the least Node.js 18+.
• Set up a package deal supervisor, like npm or yarn.
• Ensure you have a working terminal/command-line (PowerShell, Terminal, WSL, and so on). 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, you probably have a Gemini API key, you need to use that too.

export GEMINI_API_KEY="YOUR_API_KEY"

Operating our CLI Situations

After finishing the set up and authentication processes, customers will instantly start to reap the benefits 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, for example, over the person’s native listing, will present:

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