If you’re trying to run nodemon from the terminal and see the error:
nodemon: command not found, it usually means the nodemon package is not installed globally or your terminal can’t find it in your system’s PATH.
Solution 1: Install nodemon Globally
You can install nodemon globally:
npm install -g nodemon
This makes it available system-wide so you can run nodemon from any directory.
Solution 2: Use npx (No Global Install Needed)
If you don’t want a global install:
npx nodemon app.js
This uses the version in your project’s node_modules folder (if installed).
Solution 3: Check Your PATH
Make sure your global npm path is in your system’s PATH. To find it:
npm config get prefix
Make sure the output (e.g., /usr/local/bin) is in your terminal’s PATH variable.

Solution 4: Use nodemon as an NPM Script
Add this to your package.json:
"scripts": {"dev": "nodemon app.js"
}
Run with:
npm run dev
Conclusion
Install nodemon globally, use npx, or run it via npm scripts to avoid “command not found” issues in Bash.
