Hi,

Start give this exception after I upgraded my ionic version to 2.1.4

There was an error serving your Ionic application: TypeError: Cannot read property ‘hasOwnProperty’ of undefined

Please post the “scripts” stanza of your package.json. If the answer is “there isn’t one”, that’s your problem. Make it look like the one in a freshly generated project.

Same problem, this is my package.json, i’m creating a new project using the command ionic start myApp tabs

Ok, I downgrade ionic cli (1.7.6) and cordova (5.4) and all work fine…

I’m sorry for reply about ionic 1 in this ionic 2 post.

Faulty line is return packageJsonContents.hasOwnProperty('scripts') so something about a json config file.
I just created a package.json with empty json {} in the root of the project and it fixed the problem.
Seems like ionic cli 2.x uses now ionic.config.json but npm still needs package.json
