reactjs - React-chartjs not working -

i'm trying use react-chartjs within project, doesn't seem work...

i'm using react-router load page (home):

import react 'react';  import { textfield, raisedbutton } 'material-ui';  import { history } 'react-router';  import chart './widgets/chart.js';      const home = react.createclass({        getinitialstate() {          return {          };      },        componentdidmount() {      },        togglenotification() {        },        render() {            return (              <div>                  <chart/>              </div>          )      }  });    export default home;

and chart refers file:

import react 'react';  import chart 'chart.js';  import {linechart} 'react-chartjs';    function rand(min, max, num) {      var rtn = [];      while (rtn.length < num) {          rtn.push((math.random() * (max - min)) + min);      }      return rtn;  }    const chartwidget = react.createclass({        getinitialstate() {          return {              chartdata : {              labels: ["january", "february", "march", "april", "may", "june", "july"],              datasets: [                  {                      label: "my first dataset",                      fillcolor: "rgba(220,220,220,0.2)",                      strokecolor: "rgba(220,220,220,1)",                      pointcolor: "rgba(220,220,220,1)",                      pointstrokecolor: "#fff",                      pointhighlightfill: "#fff",                      pointhighlightstroke: "rgba(220,220,220,1)",                      data: [5, 8, 2, 0, 1, 2, 0]                  },                  {                      label: "my second dataset",                      fillcolor: "rgba(151,187,205,0.2)",                      strokecolor: "rgba(151,187,205,1)",                      pointcolor: "rgba(151,187,205,1)",                      pointstrokecolor: "#fff",                      pointhighlightfill: "#fff",                      pointhighlightstroke: "rgba(151,187,205,1)",                      data: [-2, -5, 0, -3, -1, 0, -1]                  }              ]          }};      },        componentdidmount() {      },        togglenotification() {        },        render() {          return (                  <linechart data={this.state.chartdata} redraw width="600" height="250" />          )      }  });    export default chartwidget;

error i'm getting:

can tell me did wrong?

using:
webpack
hotloaders
react.js
react-router
react-chartjs material-ui

try import linechart way instead:

const linechart = require('react-chartjs').line;

and remove:

import {linechart} 'react-chartjs';
