Question

我制作了自己的第一个项目，并尝试构建我的应用程序并在编译后启动它。当我在 ts-node 的开发模式下使用我的应用程序时，没有问题，没有错误，一切正常。现在我使用构建脚本进行编译：npm run start（检查下面的 package.json），在我的应用程序在 dist 文件夹中构建后，我尝试启动它，我看到以下错误：

不能在模块外使用 import 语句意外的令牌“导出”文件：./src/modules/authentication/events/authentication.event.ts 不能在模块文件外使用 import 语句：./src/modules/users/events/user.event.ts

我在网上查过，但我看到很多回复：在 package.json 中添加 type:module，更改打字稿选项，...但似乎没有任何效果，我在不同的回复中有点迷失看到了。

我让你看看我的配置文件有没有问题：

感谢您的帮助

在包 js 中将类型设置为模块通常可以解决此问题。你确定你设置对了吗？

请尝试再次设置它，将其添加到 package.json 的顶层，如下所示：

{
  ...
  "main": "index.js",
  "type": "module",
  ...
}

这里的“主要”部分只是为了澄清“类型”属性的去向。

编译出错不能在模块外使用导入语句
