当我在AOT模式下编译应用程序时：

$ng build –aot

我收到这个错误：

路径node_modules / @ acme / library / src / library / library指向library.d.ts文件,该文件存在于模块目录中.

如果我从外部包中完全删除键入信息,则应用程序将编译并正常工作.此外,如果我手动将所有打字合并到一个index.d.ts文件中,编译就完成了.

我认为编译器解析类型定义文件的方式有些不对,看起来因为某些原因它没有查找扩展名为.d.ts的文件.

更新1

外部模块@ acme / library也是由我开发和预编译的.它是一个简单的TypeScript库,包含一些导出的类和函数.它没有使用像Angular那样的装饰和东西.

它的package.json包含以下字段：

"es2015": "index.es2015.js","main": "index.min.js","module": "index.es5.js","typings": "index.d.ts",

所有提到的文件都存在于包的根目录中.

更新2

经过进一步调查,看起来问题是由依赖注入引起的.请参阅下面的示例.

我正在使用自定义工厂提供程序,以便将一个Library实例注入组件的构造函数.

libraryFactory函数是从外部模块导入的,它看起来像这样：

export function libraryFactory(): Library {
  const dep1 = new Dep1();
  const dep2 = new Dep2();
  return new Library(dep1,dep2);
}

失败的例子

import {Component} from '@angular/core';
 
import {Library,libraryFactory} from '@acme/library';
 
 
@Component({
  selector: 'app-foo',templateUrl: './foo.component.html',providers: [
    {
      provide: Library,useFactory: libraryFactory
    }
  ]
})
export class FooComponent {
 
  constructor(public library: Library) {
  }
 
}

工作实例

但是,如果我摆脱DI它编译并正常工作：

import {Component} from '@angular/core';
 
import {Library,templateUrl: './foo.component.html'
})
export class FooComponent {
 
  public library: Library;
 
 
  constructor() {
    this.library = libraryFactory();
  }
 
}

什么可能导致这个问题？

如果需要,我会很乐意提供更具体的信息.
