Claude Code Installation

Claude Code works in the terminal, desktop app, and IDE. For local Passion8 access, install → enter the Passion8 URL, API key, and enabled model → restart → verify a request. Vendor OAuth login is not required for this setup. Installation steps for each entry point follow; if you mainly work in an editor, go directly to Claude Code’s official VS Code extension setup.

After installing the CLI, continue to Configure Claude Code. For the full CLI, PATH, and terminal shortcuts, see CLI and terminal reference.

#Install the CLI

curl -fsSL https://claude.ai/install.sh | bash
exec $SHELL -l
claude --version

irm https://claude.ai/install.ps1 | iex
claude --version

#Install the desktop app

Download the version for your system from the official installation page, follow the installer, and confirm you can select or open a local project.

Official Claude Code installation

#Install the official IDE extension

1. Search for Claude Code in your IDE's extension marketplace.
2. Install the official extension published by Anthropic.
3. Restart the IDE, open a project, and confirm the Claude Code panel or command is available.

#Verify installation

From a project directory, run:

claude --version

A version number confirms that the CLI is installed. Complete Passion8 configuration, open a new terminal, and then run claude in your project or use the guide’s test request. A login prompt before configuration does not mean you need a vendor account; finish the API-key setup first.
