爲什麼WWW文件夾爲空的應用程序創建使用Ionic2

Question

我用命令創建一個應用程序Ionic2：

離子開始拉胡爾--v2

是 CD拉胡爾
離子後服務

但顯示我錯誤的瀏覽器： 錯誤：ENOENT：沒有這樣的文件或目錄，打開'/usr/local/n/versions/node/7.0.0/rahul/www/index.html'

然後我檢查了WW w文件夾，我發現除了一個名爲.gitkeep的文件外沒有任何東西。

NPM -v = 3.10.8
節點-v = V7.0.0
科爾多瓦-v = 6.4.0
離子-v = 2.1.0-beta.3

的package.json ：

{ 
    "name": "ionic-hello-world", 
    "author": "Ionic Framework", 
    "homepage": "http://ionicframework.com/", 
    "private": true, 
    "scripts": {

    },

    ], 
    "cordovaPlatforms": [] 
} 

Answer 1

出事了與我的Ionic2安裝。

這裏是安裝ionic2的步驟，如果您已經安裝離子。 更新節點 更新NPM

然後最重要的是更新的離子和科爾多瓦同時這樣的：由一個我安裝的離子和科爾多瓦之一： NPM安裝-g離子科爾多瓦

我做了錯誤的。

Answer 2

更新您的package.json下面你這麼離子服務將工作 這裏script對象被改變，那麼一切都按預期。 但我仍在研究它爲什麼不自動更新。
