Question

尝试将Angular从4.0.0更新到4.0.1。

所有内容编译都很好，但在打开网站时会崩溃

Uncaught Error: Can't resolve all parameters for SomeData: (?, ?, ?).

班级SomeData：

import { Injectable } from '@angular/core';
import { ReplaySubject } from 'rxjs';
import { SomeModel } from './some.model';

@Injectable()
export class SomeData extends ReplaySubject<SomeModel> {
    public name: string = '';
}

类SomeModel是一个通常的类，即使没有任何装饰器。

我该如何解决？看起来像Angular团队doesn't write about any breaking changes between 4.0.0 and 4.0.1。

这就是我使用的（当然不是全部）：

"dependencies": {
  "@angular/animations": "4.0.1",
  "@angular/common": "4.0.1",
  "@angular/compiler": "4.0.1",
  "@angular/core": "4.0.1",
  "@angular/forms": "4.0.1",
  "@angular/http": "4.0.1",
  "@angular/platform-browser": "4.0.1",
  "@angular/platform-browser-dynamic": "4.0.1",
  "@angular/platform-server": "4.0.1",
  "@angular/router": "4.0.1",
  "@angularclass/conventions-loader": "^1.0.13",
  "@angularclass/hmr": "~1.2.2",
  "@angularclass/hmr-loader": "~3.0.2",
  "ngc-webpack": "^1.2.0",
  "rxjs": "~5.2.0",
  "zone.js": "~0.8.5"
},
"devDependencies": {
  "@angular/compiler-cli": "4.0.1",
  "ts-loader": "^2.0.3",
}

我认为ngc-webpack问题可以在问@angular/compiler-cli@^2.4.1时出现，但它适用于4.0.0。无论如何，我不知道如何更换这个模块。

Angular 4.0.1无法解析所有参数
