Environment Setup.

A complete guide to setting up your development environment. Follow these steps in order — each tool builds on the previous one.

First, select your operating system:

# What is the Terminal?

The terminal (also called "command line" or "console") is a text-based way to control your computer. Instead of clicking buttons and icons, you type commands. It looks intimidating at first, but it's actually simpler — one command can do what would take 10 clicks in a graphical interface.

Every command you'll copy from this page goes into the terminal. You paste it, press Enter, and the computer does the rest.

How to Open the Terminal

  • Spotlight Search (Fastest): Press ⌘ Cmd + Space, type "Terminal", press Enter
  • From Finder: Applications → Utilities → Terminal
  • Tip: Once you install iTerm2 (below), use that instead — it's better

Anatomy of a Command

brew install node
  • brew — The program you're running (Homebrew package manager)
  • install — What you want it to do (install something)
  • node — What to install (Node.js)

Commands follow this pattern: program action target. Once you see the pattern, they all make sense.

# Verify Installation

After installing everything, run these commands to make sure it all worked:

node -v Should show: v20.x.x or higher
git --version Should show: git version 2.x.x
python3 --version Should show: Python 3.x.x
claude --version Should show: claude-code version x.x.x

If any command says "not found", go back and install that tool again. Make sure to open a new terminal window after installing.

# Essential Terminal Shortcuts

These keyboard shortcuts will save you hours. Memorize them.

Navigation

  • ⌘ + C — Cancel current command
  • ↑ / ↓ — Previous/next command from history
  • Tab — Autocomplete file/folder names
  • ⌘ + L — Clear screen

Editing

  • ⌘ + A — Go to start of line
  • ⌘ + E — Go to end of line
  • ⌘ + U — Delete entire line
  • ⌘ + K — Delete to end of line

VS Code Terminal

  • ⌘ + ` — Toggle terminal panel
  • ⌘ + Shift + ` — New terminal
  • ⌘ + Shift + P — Command palette

# Common Issues

"command not found"

The tool isn't installed, or your terminal doesn't know where to find it. Try:

  • Close and reopen your terminal (some installs need this)
  • Make sure you installed the tool correctly
  • On Windows, make sure you're running inside Ubuntu, not PowerShell

"permission denied"

You need administrator access. Add sudo before the command:

sudo apt install git

It will ask for your password. When you type, nothing appears — that's normal for security. Just type and press Enter.

"EACCES: permission denied" (npm)

npm is trying to install to a protected folder. Fix it once with:

sudo chown -R $USER /usr/local/lib/node_modules
