提前感谢您的帮助。我正在尝试使用打字稿在 Angular 2 中获得本地存储访问权限。我正在使用 npm 包 angular2-localstorage。我有 angular.io “英雄之旅” 工作（没有太多样式）。我按照https://www.npmjs.com/package/angular2-localstorage的说明进行操作。将建议的代码添加到我的 app.module.ts 文件后，我尝试使用 运行npm start，并得到以下编译错误：

node_modules/angular2-localstorage/LocalStorageEmitter.ts(46,9): error TS2305: Module '"/Users/joshuaforman/Documents/CodeCraft/a2quickstart/a2-angular/node_modules/@angular/core/src/facade/lang"' has no exported member 'Type'.
node_modules/angular2-localstorage/LocalStorageEmitter.ts(47,9): error TS2305: Module '"/Users/joshuaforman/Documents/CodeCraft/a2quickstart/a2-angular/node_modules/@angular/core/src/di"' has no exported member 'provide'.

您可以在此处查看所有代码：https ://github.com/joshuaforman/angular2-quickstart

此外，这是完整的 app.module.ts 文件（我更改的唯一一个导致错误发生的文件）：

import { NgModule }       from "@angular/core";
import { BrowserModule }  from "@angular/platform-browser";
import { FormsModule }    from "@angular/forms";
import { HttpModule }    from "@angular/http";

// added for LocalStorage
// followed instructions here: https://www.npmjs.com/package/angular2-localstorage
import { LocalStorageService, LocalStorageSubscriber } from "angular2-localstorage/LocalStorageEmitter";

// Imports for loading & configuring the in-memory web api
import { InMemoryWebApiModule } from "angular2-in-memory-web-api";
import { InMemoryDataService }  from "./in-memory-data.service";

import { AppComponent }        from "./app.component";
import { HeroDetailComponent } from "./hero-detail.component";
import { HeroesComponent }     from "./heroes.component";
import { HeroService }         from "./hero.service";
import  { DashboardComponent } from "./dashboard.component";

import { routing } from "./app.routing";

@NgModule({
  imports: [
    BrowserModule,
    HttpModule,
    InMemoryWebApiModule.forRoot(InMemoryDataService),
    FormsModule,
    routing
  ],
  declarations: [
        AppComponent,
        HeroesComponent,
        HeroDetailComponent,
        DashboardComponent
  ],
  bootstrap:    [ AppComponent ],
  providers:    [
        HeroService,
        LocalStorageService // added for Local Storage
  ]
})
export class AppModule {
  // added for Local Storage
  constructor(storageService: LocalStorageService) {}
}

我为实现包含文本“LocalStorage”的本地存储而添加的每一行都有注释。如果您注释掉这三行，编译和运行时就可以正常工作。

此时，我只想能够编译成功。谢谢。

注意：这是我在堆栈上的第一个问题。过去我在这里找到了很多答案，并且在提出这个问题时我已尽力遵循惯例。欢迎任何关于我在提问时应该做些什么的富有成效的反馈。

Angular2-LocalStorage 不再维护，您必须使用另一个库，直到该库获得活跃的维护者。我推荐 Angular2 Cool Storage

从 node_modeule "angular2-localstorage" 替换 "LocalStorageEmitter.ts" 中的这一行

import {Type} from "@angular/core/src/facade/lang";
import {provide} from "@angular/core/src/di";
import {ComponentRef} from "@angular/core";

export function LocalStorageSubscriber(appPromise: Promise<ComponentRef<any>>) {
    appPromise.then((bla) => {
        bla.injector.get(<Type>LocalStorageService);
    });
}

有了这个。

import {Type} from "@angular/core/src/type";
import {Provider} from "@angular/core/src/di";
import {ComponentRef} from "@angular/core";

export function LocalStorageSubscriber(appPromise: Promise<ComponentRef<any>>) {
    appPromise.then((bla) => {
        bla.injector.get(<Type<any>>LocalStorageService);
    });
}

这对我有用...
