nodemon not found in npm

Question

I have a problem: nodemon does not run off the npm script (e.g. npm start),
but if nodemon is called on the command line outside the npm script, nodemon runs as normal.

$ nodemon server.js
14 Feb 22:59:51 - [nodemon] v1.3.7
14 Feb 22:59:51 - [nodemon] to restart at any time, enter `rs`
14 Feb 22:59:51 - [nodemon] watching: *.*
14 Feb 22:59:51 - [nodemon] starting `node server.js`

How it is called in npm script:

package.json

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

When npm start script is run:

$ npm start
> [email protected] start /home/akul/Documents/aaa
> nodemon server.js

sh: 1: nodemon: not found

I've been looking for a solution, but have not found one.

Answer 1

You can resolve this problem by adding nodemon to your package.json:

npm install nodemon --save-dev

The problem happens when nodemon does not exist in /node_modules/.bin.

Added --save-dev since it's required during development only.

Answer 2

Try to check installed global packages npm list -g --depth=0. If you will not find nodemon, - install it with flag -g or --save-dev. Don't install nodemon with flag --save, because nodemon uses only for development.

Answer 3

under your current project directory, run

npm install nodemon --save //save in package.json so that the following code cam find your nodemon

then under "scripts" in your package.json file, add "start": "nodemon app.js" (or whatever your entry point is)
so it looks like this:

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

and then run

npm start

That avoids complicate PATH settings and it works on my mac
hope can help you ;)
