我试着把我的web应用程序部署到heroku中，自从我添加了“emailjs”模块后，我就一直遇到这个问题。在那之前，我的部署工作得很好，现在我每次都遇到同样的问题。不管我怎么尝试。Heroku logs results after trying to deploy

这是我在index.js中代码：′

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

reportWebVitals();

`
问题是：当我将“import”更改为“require”时，代码会向我抛出越来越多的错误。

**这是我包。

如果你有任何建议，我会非常感谢〈3
我已经尝试了这里所写的所有解决方案："Uncaught SyntaxError: Cannot use import statement outside a module" when importing ECMAScript 6
我还试图将“导入”切换为“要求”，但没有成功。
我希望我的代码能在heroku上运行良好。
Pd：它在我的本地主机上100%正常工作。
