  2. Leave Automatically install the necessary tools unticked unless your instructor says otherwise.

macOS

Use the .pkg installer, or Homebrew:

brew install node@22

Linux

Use a version manager so you never need sudo for npm:

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

Configuration

No configuration is needed. Check the versions in a new terminal.

Verification

Run each command in a new terminal window.

node -v

→ expect v20.x or newer

npm -v

→ expect Any version number

Common errors

node works in one terminal but not another
Fix

Close all terminals and your editor, then reopen. PATH is only read when a terminal starts.
