I tried deploying the react app in heroku but it failed - reactjs

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"
}
}

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.
