javascript - <错误> ReactElementExtended.js :30 - Error when integrating "React-Slick" ReactJS Module

Question

当我集成react-slick时将 ReactJS 模块添加到我的项目中，我在 Chrome 控制台中收到以下错误。这个错误信息是什么意思？我是否错误地集成了模块？

这就是我的代码的样子:

/** @jsx React.DOM */

var React = require('react');
var Slider = require('react-slick');

var Slider = React.createClass({
    propTypes: {
        type: React.PropTypes.string        
    },
    getDefaultProps: function() {
        return {
            type: 'track'
        };
    },
    render: function() {
        var settings = {
          dots: true,
          infinite: true,
          speed: 500,
          slidesToShow: 1,
          slidesToScroll: 1
        };

        return (
            <Slider {...settings} >
                <div><h3>1</h3></div>
                <div><h3>2</h3></div>
                <div><h3>3</h3></div>
                <div><h3>4</h3></div>
                <div><h3>5</h3></div>
                <div><h3>6</h3></div>
            </Slider>
        );
    }
});

module.exports = Slider;

这就是我的 webpack.config.js 的样子:

'use strict';

var webpack = require('webpack');

module.exports = {
  devtool: 'sourcemap',
  entry: './app/index.js',
  output: {
    filename: 'bundle.js',
  },
  module: {
    loaders: [
      {
        test: /\.js$/, 
        loaders: [
          'jsx-loader?harmony'
        ]
      },
      { test: /\.jsx$/, loaders: ['jsx?harmony'] },
      { 
        test: /\.less$/, 
        loader: 'style-loader!css-loader!less-loader' 
      },
      { 
        test: /\.css$/,
        loader: 'style-loader!css-loader'
      },
      { 
        test: /\.(png|jpg|otf|eot|svg|ttf|woff)$/,
        loader: 'url-loader?limit=8192'
      } // inline base64 URLs for <=8k images, direct URLs for the rest
    ]
  }
};

和我的 package.json:

{
  "name": "webpack-howto-example",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server",

您的 React 组件类名称似乎有问题。

在您发布的代码中，您将react-slick定义为类Slider，然后用您自己的Slider组件类覆盖Slider。因此该组件尝试创建自己。

只需重命名您的 Slider 组件即可。

/** @jsx React.DOM */    
var React = require('react');
var Slider = require('react-slick');

var SimpleSlider = React.createClass({
    propTypes: {
        type: React.PropTypes.string        
    },
    getDefaultProps: function() {
        return {
            type: 'track'
        };
    },
    render: function() {
        var settings = {
          dots: true,
          infinite: true,
          speed: 500,
          slidesToShow: 1,
          slidesToScroll: 1
        };

        return (
            <Slider {...settings} >
                <div><h3>1</h3></div>
                <div><h3>2</h3></div>
                <div><h3>3</h3></div>
                <div><h3>4</h3></div>
                <div><h3>5</h3></div>
                <div><h3>6</h3></div>
            </Slider>
        );
    }
});

module.exports = SimpleSlider;
