Methods to Entry Gemini CLI?

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

System Necessities

NodeJS is a typical prerequisite for each the CLIs. You possibly can 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 put in the next prerequisite software program in your pc’s working system. First, you should set up Node.js and npm (or yarn), and each software program must 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 is not uncommon for customers to choose to run CLI instruments by way of 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 mission folder when operating the CLI instructions for Gemini, in order that the CLI can learn or write appropriately to the mission for mission recordsdata and context.

Set up Steps

1. Examine Stipulations:

• Ensure to have no less than 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 so forth). 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 it’s important to 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"

Working 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, as an illustration, over the person’s native listing, will present:

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