Environment Check

Before configuring any CLI tool, make sure your development environment meets the basic requirements.

Node.js

Most CLI tools require Node.js. Node.js 18 or newer is recommended.

# Check Node.js version
node --version
# Should print v18.x.x or later

# Check npm version
npm --version

Install on macOS / Linux

If Node.js is not installed, we recommend using nvm to manage versions:

# Install nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.0/install.sh | bash

# Install the latest LTS release
nvm install --lts

You can also download an installer directly from nodejs.org.

Install on Windows

We recommend the LTS release.

After installation, restart your terminal so node and npm are available.

Option 1: official installer (recommended)

Go to https://nodejs.org, download the Windows LTS installer (.msi), and use the default settings.

Option 2: package manager

# Winget (built into Windows 11/10)
winget install OpenJS.NodeJS.LTS

# Or Chocolatey
choco install nodejs-lts

# Or Scoop
scoop install nodejs-lts

After installation, open CMD or PowerShell and verify:

node --version
npm --version

Network

Make sure your network can reach https://model-go.com:

macOS / Linux

curl -I https://model-go.com
# Should return HTTP 200

Windows (PowerShell)

Invoke-WebRequest -Uri https://model-go.com -Method Head
# Should return StatusCode 200
