全局安装 Angular CLI

npm install npm@latest -g
npm install @angular/cli -g

创建新项目

ng new angular2Demo

启动开发服务器

cd angular2Demo
ng serve --open
#访问地址
http://localhost:4200/

/src目录中以下三个TypeScript文件

src
|--app
|   |-- app.component.ts
|   |-- app.module.ts
|--main.ts

src/app/app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',templateUrl: './app.component.html',styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'My First Angular App!';
}

src/app/app.module.ts

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

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],imports: [
    BrowserModule,FormsModule,HttpModule
  ],providers: [],bootstrap: [AppComponent]
})
export class AppModule { }

src/main.ts

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule);

angular-cli常用命令

#创建一个新项目，置为默认设置
ng new project-name
#构建/编译应用
ng build
#运行单元测试
ng test
#启动一个小型web服务器，用于托管应用
ng serve

#生成一个新的组件
