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

Answer 2

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.

Answer 3

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

Answer 4

如果你想安装全局nodemon使用SUDO，因为如果你需要是全局用户，你需要是超级用户

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, eg npx nodemon --inspect ./src/index.js 8080
