Question:

On giving ionic start myApp blank --v2 i am not able to generate package.json correctly.

http://blog.ionic.io/improvements-to-ionic-build-process/ according to this blog i tried still no better output.

Answer 1

I was using ubuntu16.04 and i forgot to add the sudo command befor that was my issue while installing to latest one.

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

Now everything works fine

Answer 2

I have run into the exact same issue. I updated ionic to reflect this

cmd ionic info

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

Note Node version is not 7.0

Start a new project sidemenu or tabs and ionic -l or ionic serve should work.

Answer 3

I was also facing this same issue, I search here in ionic forum
https://github.com/ionic-team/ionic-cli/issues/1420 Finally i came to relized that I have to do something like this-

I was missing index.html file here-
www/index.html
I just copy and paste index file to resolve this issue-
copy form src/index.html
paste here www/index.html

hopefully that will for for you as this worked for me.

OR

another way to do is just update your local setup by following this article
http://ionicframework.com/docs/intro/installation/

if you are getting error of node compatibility while installing cordova then just do it-

$ sudo npm install n -g 

to install n to manage node version.

$ sudo n latest

to install latest version of node.

$ npm install -g ionic cordova

to install cordova.
Now Create new app-

$ ionic start cutePuppyPics   

run server-

$ cd cutePuppyPics
$ ionic serve

Hope it will help too...
