Nodemon returns "command not found"

Running macOS 10.13.6 and installed nodemon 2.0.4

Typing nodemon into the terminal returns: "command not found"

Any idea what I can do?

Omri Marebera what does --force do? 

npm WARN using --force I sure hope you know what you are doing.

even after doing this I still get:

-bash: nodemon: command not found

Hey, so I was having the same problem. I had never used nodemon the way it was demonstrated in the video so I went back and did it the way I was used to using it and it worked.

Here are the steps:

  1. npm i --save-dev nodemon
  2. open up package.json and change the scripts key value as shown here:
{
  "name": "flashcards",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "devStart": "nodemon app.js" //replace whatever the default echo message with something like this. I called it devStart because that's how I learned it from a tutorial but you can call it whatever as long as the property is "nodemon NameOfYourFile.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.17.1"
  },
  "devDependencies": {
    "nodemon": "^2.0.6"
  }
}
  1. make sure to stop any running server you have and run npm run devStart (or whatever you called it)
  2. that should work :)
