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
> aaa@0.0.1 start /home/akul/Documents/aaa
> nodemon server.js

sh: 1: nodemon: not found

npm ERR! Linux 3.13.0-45-generic

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

Answer 1

NPM is used to manage packages and download them. However, NPX must be used as the tool to execute Node Packages

Try using NPX nodemon ...

Hope this helps!

Answer 2

heroku runs in a production environment by default so it does not install the dev dependencies.

if you don't want to reinstall nodemon as a dependency which I think shouldn't because it's right place is in devDependencies not in dependencies.

instead, you can create a two npm script to avoid this error by running nodemon only in your localhost like that:

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

and when you want to run the project locally just run in your terminal npm run start:dev and it will load app.js by nodemon.

while in heroku npm start runs by default and load app.js from a normal node command and you get rid of that error.

Answer 3

First install nodemon to your working folder by

npm install nodemon

Add the path of nodemon to the path variable of Environment Variable of System environment. In my case the path of nodemon was.

C:\Users\Dell\Desktop\Internship Project\schema\node_modules\.bin

It worked for me.

Answer 4

You have to simply installed it globally. npm install -g nodemon

Answer 5

--save, -g and changing package.json scripts did not work for me. Here's what did: running npm start (or using npx nodemon) within the command line. I use visual studio code terminal. When it is successful you will see this message:

[nodemon] 1.18.9
[nodemon] to restart at any time, enter rs
[nodemon] watching: .
[nodemon] starting node app.js

Good luck!

Answer 6

This solution had worked for me:

I assume that you have installed nodemon globally. If it's done follow this steps:

open your .bash_profile file:

nano .bash_profile

past this to add a new alias in your bash profile:

alias nodemon='~/.npm-global/lib/node_modules/nodemon/bin/nodemon.js'

Now you can use nodemon command anywhere.
