reactjs - 如何使用 webpack 使 create-react-app 支持 .mjs 文件？

Question

我正在尝试使用这个 twitch npm 包( https://www.npmjs.com/package/twitch )，并且在通过 creat-react-app/react-scripts 部署时遇到了一些问题。
根据我的理解，与 create-react-app 捆绑的 webpack 配置不喜欢这个 npm 包正在使用的 .mjs 文件。因此，当我尝试构建应用程序时，出现以下错误。

./node_modules/twitch/es/API/Kraken/Channel/ChannelApi.mjs
app_1    | Can't import the named export 'Cacheable' from non EcmaScript module (only default export is available)

如果我手动删除了“es”文件夹，那么构建工作并且一切都按预期运行。但是，这不是真正的解决方案，因为当我推送到生产并在那里部署时，会重新安装节点模块并且构建再次失败。
构建过程并不是我的强项，在谷歌搜索一段时间后我无法找到解决方案。如果有人可以提供帮助或可以指出我正确的方向，那将不胜感激!
如果有帮助，这是我的 package.json

在 this GitHub comment 提出的建议是添加 react-app-rewired 到您的项目，然后使用此 config-overrides.js文件:

module.exports = function override(config) {
  config.module.rules.push({
    test: /\.mjs$/,
    include: /node_modules/,
    type: "javascript/auto"
  });

  return config;
}

在我的项目中，我已经在使用 react-app-rewired ，所以我只是从那个片段中添加了规则。此解决方法为我修复了错误。
在 twitch的具体情况下库，作者建议尝试使用 @next发布，尽管我还没有亲自验证该解决方案。
