🤔Troubleshooting the ‘nodemon Command Not Recognized’ Error in Node.js

If you’re encountering the ‘nodemon command not recognized’ error in the terminal for your Node.js server, it likely means that Nodemon is not installed globally or is not in your system’s PATH.

Here are some steps to fix this issue:

1. Install Nodemon Globally:

Make sure you have Nodemon installed globally by running the following command:

npm install -g nodemon

The -g flag installs Nodemon globally, making it accessible from any directory in your terminal.

2. Check Node.js Installation:

Ensure that Node.js and npm are installed correctly. Sometimes, issues with the Node.js or npm installation can cause problems. 

You can check the versions with:

node -v
npm -v

If these commands don’t return the versions, you may need to reinstall Node.js and npm.

3. Verify Nodemon Installation:

After installing Nodemon, make sure it’s installed correctly by running:

nodemon -v

This should display the version of Nodemon installed. 

If you still get the ‘nodemon command not recognized’ error, it means Nodemon is not in your system’s PATH.

4. Check System PATH:

Ensure that the directory where Nodemon is installed is included in your system’s PATH. This allows the terminal to find the ‘nodemon’ executable.

5. Check npm Scripts:

If you are running your Node.js server using npm scripts, make sure the ‘nodemon’ command is correctly specified in the “scripts” section of your package.json file. For example:

"scripts": {
  "start": "nodemon server.js"
}

6. Try Without Global Installation:

If you prefer not to install Nodemon globally, you can also install it as a development dependency in your project:

npm install --save-dev nodemon

Then, you can use it in your npm scripts:

"scripts": {
  "start": "nodemon server.js"
}

After applying these steps, you should be able to use the ‘nodemon’ command in your terminal without encountering the error.
