Error when I try to load ScrollBarWrapper

[artsx]

Hello, I want try your module and I've error :
build.js:15397 Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components). Check the render method ofProfil.

build.js:14954 Uncaught Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. Check the render method ofProfil.

My code source :

import React from 'react';
import {
  Grid,
  Cell
} from "react-mdl";
var ScrollbarWrapper = require('react-scrollbar').ScrollbarWrapper;
var ProfilHeader = require('./children/profilHeader/ProfilHeader.js');
var ProfilExperiences = require('./children/profilExperiences/ProfilExperiences.js');
var ProfilEducations = require('./children/profilEducations/ProfilEducations.js');
var ProfilHobbies = require('./children/profilHobbies/ProfilHobbies.js');
var ProfilSkills = require('./children/profilSkills/ProfilSkills.js');
var ProfilLanguages = require('./children/profilLanguages/ProfilLanguages.js');
import './styles/less/Profil.less';

var Profil = React.createClass({

    render: function() {
        return (
          <ScrollbarWrapper>
            <Grid className="searchList" style={{ paddingRight: '15px'}}>
              <Cell col={12} tablet={12} phone={12}>
                <div className="profil">
                  <ProfilHeader />
                  <ProfilExperiences />
                  <ProfilEducations />
                  <ProfilHobbies />
                  <ProfilSkills />
                  <ProfilLanguages />
                </div>
              </Cell>
            </Grid>
          </ScrollbarWrapper>
        );
    }
});

module.exports = Profil;

Any idea ?

it's ok, I've changed import by :
import ScrollbarWrapper from 'react-scrollbar';

[artsx]

hmm, with this syntax, it is the module react-scrollbar that is considered, how is added .ScrollBarWrapper variable with this syntax like
var ScrollbarWrapper = require('react-scrollbar').ScrollbarWrapper;

Failed to compile.

For ES6 it would be import { ScrollbarWrapper } from 'react-scrollbar'
