javascript - 如何为 rc5 配置 angular-cli 项目？

Question

尝试安装 angular-cli 以使用 angular 2 rc5，我遇到了一些错误:

找不到名称“Promise”

我已经安装了“npm install -g angular-cli@webpack”，但他似乎没有安装 typings，所以 webstorm 不知道“Promise”。

我尝试过但没有成功的:

1.我安装了“npm install typings --save”但没有任何变化。

2.在我启用的webstorm项目配置中:(没有帮助)

1. Use typescript service (Experimental)
2. Enable typescript compiler
2.1 Track changes
2.2. Use tsconfig.json

3.在 tsconfig 中，我将目标从 es5 更改为 es6，现在 webstorm 识别出 promise/then/catch 但 typescript 抛出他不知道的错误，现在我在每个组件的每个类上都面临新的错误:

export class AppComponent <-- ERROR
{

}
export class AppModule <-- ERROR
{

}
Error:(8, 14) TS1219:Experimental support for decorators is
a feature that is subject to change in a future release.
Set the 'experimentalDecorators' option to remove this warning.

这很奇怪，因为在 tsconfig.json 中:“experimentalDecorators”:是的。即使是假的，也没有变化。

ngrx 安装错误和警告:

在另一个主题中，当尝试安装 ngrx/core 时:'npm install @ngrx/core --save'

安装结束是:

....
....
`-- UNMET PEER DEPENDENCY typescript@2.0.0       <<-- In red color

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1
.0.14
npm WARN @angular/tsc-wrapped@0.2.2 requires a peer of typescript@^1.9.0-dev but none

我在安装时收到相同的警告:'npm install @ngrx/store --save'。

我在 app.module.ts 的导入数组中添加了:'StoreModule.provideStore({EmptyReducer})'。在“ng serve”之后，我在控制台中收到以下警告:

我项目中的一些代码(它是空项目):

应用程序模块.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule, ApplicationRef } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import {StoreModule} from "@ngrx/store";

import { ActionReducer, Action } from '@ngrx/store';

export const EmptyReducer: ActionReducer<number> = (state: number = 0, action: Action) => {
  switch (action.type) {
    default:
      return state;
  }
}

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    CommonModule,
    FormsModule,
    StoreModule.provideStore({EmptyReducer})
  ],
  providers: [],
  entryComponents: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {

}

tsconfig.json:

  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,

您应该转到 src/tsconfig.json 并将目标从“es5”更改为“es6”。

希望对你有帮助
