Question

我使用命令创建了一个Ionic2应用程序：

离子启动rahul --v2

之后 cd rahul
离子服务

但它在浏览器上显示错误：错误：ENOENT：没有这样的文件或目录，打开＆＃39; /usr/local/n/versions/node/7.0.0/rahul/www/index.html'

然后我检查了www文件夹，我发现除了一个名为.gitkeep的文件外什么都没有。

npm -v = 3.10.8
node -v = v7.0.0
cordova -v = 6.4.0
离子-v = 2.1.0-beta.3

的package.json：

  "author": "Ionic Framework",
  "homepage": "http://ionicframework.com/",
  "private": true,
  "scripts": {

更新你的package.json，如下所示离子服务将起作用这里script对象被更改，然后一切按预期工作。但我仍在研究为什么它不会自动更新。

Answer 2

我的Ionic2安装出了问题。

如果您已安装ionic，则安装ionic2的步骤如下。更新节点更新npm

然后最重要的是同时更新离子和cordova，如： npm install -g ionic cordova

我做的错误是：我逐个安装了离子和cordova。

为什么www文件夹对于使用Ionic2
