I tried deploying the react app in heroku but it failed

Question

This is the error that I got. It says run the npm bugs reminderpro. I did that but nothing works. My code has sfcookies from npm. When i deployed earlier it said that sfcookies did not download.... something like that. So i tried typing sfcookies on package.json under dependencies but that did not work too. Now is there a SPECIFIC way to put these on heroku, am i missing somehting. (I used create-react-app for initial installation)

This is my package.json:

{
  "name": "reminderpro",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "moment": "^2.18.1",
    "react": "^15.6.1",
    "react-dom": "^15.6.1",
    "react-redux": "^5.0.6",
    "react-scripts": "1.0.13",
    "redux": "^3.7.2"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

Answer 1

Is the build script being called before the install?

You should show the code for your package.json as I could better get a grasp of the order Heroku calls your scripts.
