reactjs - 图标应该有 `type` 属性或 `component` 属性或 `children`？

Question

Warning: Icon should have `type` prop or `component` prop or `children`. 
How to troubleshoot the issue？

import React from 'react';
import { bindActionCreators,createStore } from 'redux';
import { Link, browserHistory } from 'react-router';
import { connect } from 'react-redux';
import actions from '../../actions/information/inforResource.js';
import Dropdown from '../../components/common/dropdown.js';
import ListSearch from '../../components/common/listSearch.js';
import moment from 'moment';
import {Modal, Icon, Button, Row, Col, Form, DatePicker, Select, Table, Input, Pagination, Menu, Tooltip, Drawer, message, Avatar} from 'antd';

<Icon type="delete"/>

我删除了页面的图标标签，仍然报错。我删除了子组件中的Icon标签，仍然报错。
