javascript - 要求(img 路径)不工作/找不到模块 "."reactjs

Question

您好，我正在尝试使用 react.js 将一组图像从 this.state 映射到图像标签。我遇到了错误:“找不到模块‘.’”

这里是错误: 错误:找不到模块“。” webpackMissingModule src/components/thumbnails.js:26

 23 | }
  24 | render(){
  25 |  const thumbnailimg = this.state.thumbnail_vids.map((img,i)=>{
> 26 |      let image = require(img);
  27 |      return(<img key={i}  className="thumbimg" src={image}/>)
  28 |     })
  29 |  return(

完整代码如下:thumbnails.js

import React, { Component } from "react";
import { render } from "react-dom";

class Thumbnails extends Component {
    constructor(props){
        super(props);
        this.state = {
            thumbnail_vids: ['../thumbnails/asthma_1.jpeg','../thumbnails/asthma_2.jpeg','../thumbnails/asthma_3.jpeg']
        }
    }
    render(){
        const thumbnailimg = this.state.thumbnail_vids.map((img,i)=>{
            let image = require(img);
            return(<img key={i}  className="thumbimg" src={image}/>)
        })
        return(
            <div>
                <span className="thumbtable">
                <img src={require("../thumbnails/asthma_1.jpeg")} />
                    {thumbnailimg}
                </span>
            </div>
        )
    }
}

export default Thumbnails;

这是我的 src 文件夹的项目结构(尽管我已经抽象了与手头问题无关的任何内容):

我正在使用 create-react-app

尝试将 require 语句移动到您的状态，如下所示:

this.state = {
  thumbnail_vids: [
    require('../thumbnails/asthma_1.jpeg')
  ]
  ...
