我已经将所有内容从一个工作项目（最终的热重载示例）转移到了我现有的使用梯形cms的项目中。我卸载了我项目中的所有dev依赖项，并将工作项目中的所有确切依赖项都安装到了我的（webpack，babel等）中。
由于某些原因，web.config.js文件无法解析es6语法
export default
哪个出现此错误：
- configuration has an unknown property 'default'.
如果我切换到以下选项，它将起作用：
const config = ...
module.exports = config;
在我项目的其他地方，我使用了其他es6语法，并且可以使用...
这是package.json中的依赖项，它与具有'export default'语法的示例项目完美配合。
