I initially got an error, but it was because I was in the wrong directory to run the command. In the right directory, I was able to run npm install. But I got an error on npm start. I had to manually run 'npm install nodemon --save' and then things worked as expected. (In the event you resolved this weeks ago, I thought it might be applicable to other people who have errors)

Hi Mohamed.

You may need to check that npm is installed for your project either globally so you can use it for your project or that the projects JSON file is included for your project.

You can check npm is ready by typing npm -v in your terminal.

Also in the root of your project you can make sure the project dependencies are correctly installed using npm install.

Let us know if this helps! :-)

I'm also getting an error when I attempt to run this project. I know why, however.

package.json for the project

{
  "name": "express-template",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "nodemon ./bin/www"
  },
  "dependencies": {
    "debug": "~2.6.9",
    "express": "~4.16.1",
    "morgan": "~1.9.1",
    "pug": "^2.0.4"
  }
}

This start script requires nodemon but it is not listed in the dependencies. I purposely do not install dependencies like nodemon to my root, since this is a security risk. Adding nodemon to the dependencies would probably be a good idea.

For those facing the same issue, run npm install -D nodemon and you should be good to go.
