angular - 意外值 ToasterModule 请添加 @NgModule 注释

Question

我已经在这里工作了 2.5 个小时，并且浏览了多个帖子。在 https://github.com/angular/angular/issues/15763 上尝试了几个建议，这让我很沮丧，因为上述错误的来源似乎不同。

我在 angular 5 上构建时，出现错误:

ERROR in : Unexpected value 'ToasterModule in .../node_modules/angular5-toaster/dist/bundles/angular5-toaster.umd.js' imported by the module 'AppModule in ../src/app/app.module.ts'. Please add a @NgModule annotation.

库没有自己的 node_modules 副本。它自己的 tsconfig.js 文件是:

{
  "compilerOptions": {
    "target": "es2015",
    "module": "es2015",
    "moduleResolution": "node",
    "sourceMap": true,

    "experimentalDecorators": true,
    "removeComments": false,

  },
  "include": [
    "angular5-toaster.ts",
    "src/**/*"
  ],
  "exclude": [
      "node_modules",
      "bundles"
    ]
}

angular5-toaster/package.json(部分):

我的 app.module.ts:

        AppRoutingModule

export class AppModule {}

我注意到 angular5-toaster(版本 1.0.2)没有添加到上面的依赖项列表中，但添加它也没有任何区别。

可能是什么问题？我将不胜感激，因为我可能会在其他图书馆遇到同样的问题。

这似乎是 AoT 构建和 angular5-toaster 的一个特殊问题.

我通过切换到 ng2-toastr 解决了这个问题看起来更稳定并提供相同的功能。
