Question

我刚刚创建了一个新项目ionic start blank --v2，我给了ionic serve。在我的浏览中，我收到如下错误

错误：ENOENT：没有此类文件或目录，请打开＆＃39; /home/panini/myApp/www/index.html'。

这是ionic serve

中cmd的输出

Running live reload server: http://localhost:35729
Watching: www/**/*, !www/lib/**/*, !www/**/*.map
√ Running dev server:  http://localhost:8100
Ionic server commands, enter:
  restart or r to restart the client app from the root
  goto or g and a url to have the app navigate to the given url
  consolelogs or c to enable/disable console log output
  serverlogs or s to enable/disable server log output
  quit or q to shutdown the server and exit

ionic $

我在离子服务器中找不到任何gulp文件监视

这是我的package.json文件

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

这是我的离子信息结果

Your system information:

Cordova CLI: 6.3.0
Ionic Framework Version: 2.0.0-rc.2
Ionic CLI Version: 2.1.0
Ionic App Lib Version: 2.1.0-beta.1
OS: Distributor ID: Ubuntu Description: Ubuntu 16.04.1 LTS 
Node Version: v6.0.0

注意

根据这个https://github.com/driftyco/ionic-cli/issues/1420讨论，当我使用下面这个对象进行更新时，package.json中的脚本对象不匹配

"scripts": {
"build": "ionic-app-scripts build",
"watch": "ionic-app-scripts watch",
"serve:before": "watch",
"emulate:before": "build",
"deploy:before": "build",
"build:before": "build",
"run:before": "build"
}

问题：

在给予离子启动myApp空白时--v2我无法正确生成package.json。

http://blog.ionic.io/improvements-to-ionic-build-process/根据这个博客我尝试过没有更好的输出。

Answer 1

我使用的是ubuntu16.04，我忘记在安装到最新版本时添加了sudo命令，这是我的问题。

sudo npm install -g ionic@latest
sudo npm install @ionic/app-scripts@latest

现在一切正常

Answer 2

我遇到了完全相同的问题。我更新了离子来反映这个

cmd离子信息

Cordova CLI: 6.4.0 
Ionic CLI Version: 2.1.12
Ionic App Lib Version: 2.1.7
ios-deploy version: 1.9.0 
ios-sim version: 5.0.11 
OS: macOS Sierra
Node Version: v6.9.1
Xcode version: Xcode 8.1 Build version 8B62

注意节点版本不是7.0

启动新项目 sidemenu 或标签，离子-l或离子服务应该有效。

Answer 3

我也面临同样的问题，我在离子论坛上搜索 https://github.com/ionic-team/ionic-cli/issues/1420 最后我开始重申我必须做这样的事情 -

我在这里缺少index.html文件 -
www/index.html
我只是复制并粘贴索引文件来解决这个问题 -
复制表格src/index.html
粘贴www/index.html

希望这对你有用，因为这对我有用。

OR

另一种方法是按照本文左右更新本地设置 http://ionicframework.com/docs/intro/installation/

如果您在安装cordova时遇到节点兼容性错误，那么就这样做 -

$ sudo npm install n -g

安装n以管理节点版本。

$ sudo n latest

安装最新版本的节点。

$ npm install -g ionic cordova

安装cordova。
现在创建新的应用程序 -

$ ionic start cutePuppyPics

运行server-

$ cd cutePuppyPics
$ ionic serve

希望它也会有所帮助......

错误：ENOENT：没有这样的文件或目录，在ionic2
