## Prerequisites

To follow this guide, you should have the following installed on your system:

- Node.js: [Download and install Node.js](
- npm (Node Package Manager): npm comes bundled with Node.js

## Step 1: Check if nodemon is installed

Before we proceed, let's first check if nodemon is installed on your system. Open your terminal and run the following command:

$ nodemon -v

If nodemon is installed, you will see the version number. If not, you will see the error zsh: command not found: nodemon.

Step 2: Install nodemon globally

To install nodemon globally, run the following command:

$ npm install -g nodemon

This command will install nodemon and make it accessible from any directory in your system.

Step 3: Add nodemon to your PATH

If you still encounter the error after installing nodemon globally, you need to add nodemon to your PATH. To do this, follow these steps:

  1. Find the path where nodemon is installed by running the following command:
$ npm config get prefix

This command will return the path where global npm packages are installed. Take note of the path.

  1. Open your .zshrc file in your favorite text editor:
$ nano ~/.zshrc
  1. Add the following line at the end of the file, replacing YOUR_NPM_PATH with the path obtained in step 1:
  1. Save and close the .zshrc file.

Step 4: Restart your terminal

Restart your terminal for the changes to take effect. You should now be able to use nodemon without encountering the error.
