react-css-module module not found

I'm new in react and I'm trying to build a simple application. I try react-css-modules to style it. It doesn't work, and I don't find the solution since now tooooooo much time. I think I have hard time to understand webpack and how it works... I found this similar post, but it didn't help me (module not found). I hope somebody can help me.

I try to style in the following way, and I get a white page with several red errors. Most important, I guess: "react-css-modules doesn't exist".

I installed:

npm install style-loader --save-dev
npm install css-loader --save-dev
npm install --save css-modulesify

I cut the most of the code to make it easy to read:

the component:

import React from 'react';
import CSSModules from 'react-css-modules';
var styles = require('./header.css');

class Header extends  React.Component {enter code here
  render (){
    return (
        <div  className="header">
            <h1  styleName='mainTitle'>{this.props.info.username}</h1>
        </div>  
    );
  }
}
export default CSSModules(Header, styles);

the CSS file:

.mainTitle{
    color: #aa0;
}

the package.json:
