react-踩坑记录——swiper报错！

 

 

已经在html文件中使用过，正确无误；但做成组件后（各种依赖文件引入路径确认无误）报错。

在只引入swiper.css时未报错，引入swiper.js文件后报错，如下：

 

 

错误原因，不详。

解决措施，不引入swiper.js,而是直接npm install swiper,在文件头部导入，如⬇️：

import React, { Component } from 'react';
import logo from './logo.svg';
import '../src/css/reset.css';
import '../src/css/swiper.css';
import '../src/css/slider.css';
import Swiper from 'swiper';



class Slider extends Component {
  constructor(){
    super();
    this.state = {
    };
  }
  componentDidMount(){
    var swiper = new Swiper('.swiper-container', {
      pagination: '.swiper-pagination',
      nextButton: '.swiper-button-next',
      prevButton: '.swiper-button-prev',
      paginationClickable: true,
      spaceBetween: 30,
      centeredSlides: true,
      autoplay: 2500,
      autoplayDisableOnInteraction: false
    });
  }
  render(){
    return <div className="swiper-container">
            <div className="swiper-wrapper">
                <div className="swiper-slide">Slide 1</div>
                <div className="swiper-slide">Slide 2</div>
                <div className="swiper-slide">Slide 3</div>
                <div className="swiper-slide">Slide 4</div>
            </div>
            <div className="swiper-pagination"></div>
            <div className="swiper-button-next"></div>
            <div className="swiper-button-prev"></div>
          </div>
      }
}


class App extends Component {
  render(){
    return <div>
        <Slider></Slider>
    </div>
  }
}



export default App;

 

 这时又出现了新问题，写在html 文件中预览时还能自动轮播的图片，拆成组件后只能手划动轮播。。。待解
