react-chartjs饼图无法呈现

我复制了react-chartjs文件夹并执行了以下操作:

需要在顶部的react-chartjs/pie库.我没有看到任何控制台错误,但我的饼图未呈现.我甚至尝试过这里提到的所有选项.

var PieChart = require('../../components/react-chartjs/pie');

var MyCompOnent= React.createClass({
  render: function() {
  var pieOptiOns= {
            animatable: true,
      };
  var pieData = [
              {
                  value: 300,
                  color:"#F7464A",
                  highlight: "#FF5A5E",
                  label: "Red"
              },
              {
                  value: 50,
                  color: "#46BFBD",
                  highlight: "#5AD3D1",
                  label: "Green"
              },
              {
                  value: 100,
                  color: "#FDB45C",
                  highlight: "#FFC870",
                  label: "Yellow"
              },
              {
                  value: 40,
                  color: "#949FB1",
                  highlight: "#A8B3C5",
                  label: "Grey"
              },
              {
                  value: 120,
                  color: "#4D5360",
                  highlight: "#616774",
                  label: "Dark Grey"
              }
          ];
    return 
 }
});

$(function(){
    var feedsList = Global_feedsList;
    console.log("feeds:"+feedsList); 
    React.renderComponent(
        ,
        document.getElementById('ribbon')
    );

    React.renderComponent(
            , document.getElementById('content')
    );

    React.renderComponent(
            , document.getElementById('mycomponent')
    );

})    


var pieOptiOns= {
            animatable: true,
            segmentShowStroke : true,
            segmentStrokeColor : "#fff",
            segmentStrokeWidth : 2,
            percentageInnerCutout : 0,
            animationSteps : 100,
            animationEasing : "easeOutBounce",
            animateRotate : true,
            legendTemplate : "
-legend\"><% for (var i=0; i
\"><%if(segments[i].label){%><%=segments[i].label%><%}%>
<%}%>
"
  };
