I’m following the[Ionic 2 tutorial steps](http://ionicframework.com/docs/v2/getting-started/tutorial/).

I started like this :

```
ionic start MyIonic2Project tutorial --v2 --ts

```

I encountered this problem :

```
	√ Sass compilation complete
	√ HTML copied to www/build
	√ Fonts copied to www/build/fonts

	Hash: e593a886038813766c87

	ERROR in [default] /Users/christianbonato/MyIonic2Project/node_modules/ionic-framework/animations/animation.d.ts:54:50 
	A 'this' type is available only in a non-static member of a class or interface.

	√ Webpack complete

	∆ Starting dev server.

```

The webserver launches alright, but I’d rather fix these errors,  
I don’t know if the app may suffer later.

The errors in animation.d.ts were solved [thanks to this](https://forum.ionicframework.com/t/issue-with-animation-d-ts/44312/3).

The only error left is this one :

```
ERROR in [default] /Users/christianbonato/MyIonic2Project/app/app.ts:13:42 
	Cannot find name 'Type'.

```

Any ideas on how to fix this?

The first one in app.ts can be fixed by changing the word ‘Type’ to ‘any’

Thx a lot.

For the record, where do these errors originate from? I’m a newbie to Webpack…
