一次又一次出现这个错误，运行react app时无法解决

Question

编译失败 ./src/index.js 1:39 模块解析失败：意外令牌 (1:39) 使用这些加载器处理了文件：

• ./node_modules/@pmmmwh/react-refresh-webpack-plugin/loader/index.js
• ./node_modules/babel-loader/lib/index.js 您可能需要额外的加载器来处理这些加载器的结果。

$RefreshRuntime$ = require('C:/Users/I'm-cx0140/Desktop/myapp/node_modules/react-refresh/runtime.js'); | $RefreshSetup$(module.id); | 此错误发生在构建期间，无法消除。

我的 package.json 文件

{

  "version": "0.1.0",
  "private": true,

尝试降级 react 脚本-

进入 package.json 并更改 react-scripts to 4.0.1 并输入 npm install(terminal) 并重新运行它。
