Install Claude Code

Prerequisites

Before you begin, make sure your environment meets these requirements:

  • Node.js 18+ (Node.js 22 LTS recommended)
  • npm 9+ or pnpm 9+
  • Operating system: macOS, Linux, or Windows WSL2
  • Terminal: Any terminal emulator with ANSI color support

Check your Node.js version:

terminal
bash
node --version
# Should output v18.x.x or higher

If you don't have Node.js installed, use nvm to manage versions:

terminal
bash
# Install nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

# Install Node.js 22 LTS
nvm install 22
nvm use 22

Install Claude Code

Install globally with npm:

terminal
bash
npm install -g @anthropic-ai/claude-code

Or with pnpm:

terminal
bash
pnpm add -g @anthropic-ai/claude-code

Verify the installation:

terminal
bash
claude --version

You should see a version number like 1.x.x.
