React 不会在 Safari 或 IE 或任何移动网络浏览器中加载图像

我使用 reactJS 开发了一个应用程序，它在这里启动。可以在此处找到该应用程序的源代码。该应用程序在 chrome 和 firefox 中完美运行，但在 Internet Explorer、Safari 和所有移动网络浏览器中，当我选择第二种模式时，我无法在单击框时呈现图像。

应用程序.js

import React, { Component } from 'react';

import './App.css';

import Status from'./components/Status';
import GameStatus from'./components/GameStatus';

const connery = require("./images/connery.svg");
const square = require("./images/square.svg");

class App extends Component {


  constructor(props){

    super(props)

    this.state = {

      board : Array(9).fill(null),
      player : null,
      winner : null,
      gamemode : null,
      /* array to store the ndex */
      order_ndex : []
    }

  }

  //Winning conditions
  checkWinner(){

    let winLines =
      [
        ["0", "1", "2"],

    this.checkmatch(winLines)
  }

  //Checks if the current state matches the winning condition
  checkmatch(winLines){
    let board = this.state.board;
    for (let index = 0; index < winLines.length; index++) {
      const [a,b,c]=winLines[index];
      if(board[a] && board[a] === board[b] && board[a] === board[c] ){

    this.setState({player})

  //Set the current state of the Game mode
  setGameMode(gamemode){
    this.setState({gamemode})
  }

  //Renders the boxes into DOM
  renderBoxes(){
    const isFrontend = this.state.gamemode === "Frontenddevlandia";
    return this.state.board.map(
      (box, index) => (
      <div 
        className="box" 
        key={index} 
        onClick={() => {
          this.handleClick(index);
        }}
      >
        {box === "X" && isFrontend && <img src={connery} alt="X"/>}
        {box === "O" && isFrontend && <img src={square} alt="O"/>}

    let prev = newBoard[ndex]
    newBoard[ndex] = null

          >

          </button>
        </div>
      </div>
    );
  }

export default App;

如您所见，我已经使用过require("./images/connery.svg")，我可以知道我做错了什么吗？
