我正在构建反应原生应用程序，它在 Android 和 iOS 上都成功运行。我想将 react-native 应用程序转换为网络应用程序。我尝试遵循教程：https://medium.com/@jonnykalambay/your-first-hybrid-app-in-15-minutes-react-native-on-the-web-2cc2646051e 以及一些来源（https:// /react-native-training.github.io/react-native-elements/blog/2018/12/13/react-native-web.html )。但是当我在网络上运行时，出现错误：尝试导入错误：'ApiGet'未从'./apiFetcher'导出。

我的代码：

//apiGet.js
function ApiGet(){
//some code
}

module.exports = {ApiGet}

//another file import
import {ApiGet} from './apiGet.js';
  • 我尝试了一个使用这种语法导入、导出进行测试的示例。它运行成功。我的代码同时使用 ES5 和 ES6。当我在 react-native 中运行代码时，没关系。我使用 ES5 创建了一个演示 react-native-web，也可以。
  • 我的 package.json：
