How to Fix "nodemon: command not found" or "zsh: command not found: nodemon"

The terminal shell cannot find the nodemon executable in system $PATH because nodemon was either installed locally without npx, or global npm bin directory is missing from $PATH.

nodemon: command not found

Quick Fix Checklist

  1. Instant run without installing globally: npx nodemon index.js
  2. Or run via package.json script (npm automatically injects ./node_modules/.bin into PATH during npm run)
  3. Modern Node alternative (Node 18+): Use native node --watch index.js with zero dependencies!
