nodemon command is not recognized in terminal for node js server

Question

You need to install it globally

npm install -g nodemon
# or if using yarn
yarn global add nodemon

And then it will be available on the path (I see now that you have tried this and it didn't work, your path may be messed up)

If you want to use the locally installed version, rather than installing globally then you can create a script in your package.json

"scripts": {
    "serve": "nodemon server.js"
  },

and then use

npm run serve

optionally if using yarn

# without adding serve in package.json
yarn run nodemon server.js
# with serve script in package.json
yarn run serve

npm will then look in your local node_modules folder before looking for the command in your global modules

1. Install nodemon globally:

   C:\>npm install -g nodemon
   

2. Get prefix:

   C:\>npm config get prefix
   

   You will get output like following in your console:

   C:\Users\Family\.node_modules_global
   

   Copy it.

3. Set Path.
   Go to Advance System Settings → Environment Variable → Click New (Under User Variables) → Pop up form will be displayed → Pass the following values:

   variable name = path,
   variable value = Copy output from your console
   

4. Now Run Nodemon:

   C:\>nodemon .
   

First, write npm install --save nodemon then in package.json write the followings

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

then write

npm run server

No need to install nodemon globally. Just run this npx nodemon <scriptname.js>. That's it.

I was facing the same issue. I had installed nodemon as a dev-dependency and when I tried to start the server it gave the message that

nodemon is not recognized as internal or external command, operable program or batch file

Then I installed it globally and tried to start the server and it worked!

npm install -g nodemon

Does it need to be installed globally? Do you need to be able to just run nodemon server.js ? If not, you could always just call it from your local project directory. Should be here:

node_modules/.bin/nodemon
