Answer 1

If for any reasons you are unable to set a Global PATH then under your current project directory, run

npm install nodemon --save-dev

then under "scripts" in your package.json file, add "start": "nodemon app.js" like this -

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon app.js"
}

then run

npm start

Thank u it's work for me. But I still wonder, why i've to add this "start": "nodemon app.js" on my package.json? – Pact

With that written, you'll be able to run "npm run start" and then the mapped script ( which is "nodemon app.js" will run). – Herries

Note: npm adds ./node_modules/bin to the working path, so that scripts will be able to use executable scripts installed to the local node modules... I actually have that added to my path statement as-is, so that I can use local node module bin scripts without issue. – Gallstone

If you need to install nodemon globally on mac OS, try

sudo npm install -g nodemon.

Then you'll have to enter your password. Once the installation is completed successfully, run

nodemon -v

to check nodemon version on terminal.

According to this, Create a new directory to store your global packages. So that there is no permission issue.

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'

Edit your .profile or .bash_profile to add the new location to your PATH:

export PATH=~/.npm-global/bin:$PATH

Then install the package without sudo:

npm install -g nodemon

Thanks - this worked a treat and feels organised in handling global packages :praying-hands: – Maurilia

Answer 4

If you want to install global nodemon use SUDO, because if you need to be a global user, you need to be a super user

Answer 5

The other answer is correct but my advice is that it's better to not install packages globally if you can help it, this makes your application self sufficient without relying on the environment and avoids versioning issues between applications.

npm install -D nodemon

You can now execute nodemon from scripts in package.json:

"scripts": {
   "start": "nodemon src/index.js"
}

Or you can execute it yourself using npx if you're in that directory from the terminal. npx executes local scripts, e.g. npx nodemon --inspect ./src/index.js 8080

Just run these commands and the error will get solved. Specially for MAC People:

1. sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

All set .....🎉
