Short description of the problem:

I just created a new project in Ionic 2 typescript and sidemenu as template
Everytime I run ionic serve I receive this not blocking error:

ERROR in [default] /.../scaffold-ionic/node_modules/angular2/src/facade/promise.d.ts:1:9
Cannot re-export name that is not defined in the module.

Steps to reproduce:

1. ionic start scaffold-ionic sidemenu --v2 --ts
2. ionic serve

Thanks for opening this issue with us! As this issue has more to do with our CLI than the actual framework I will be moving this issue over to that repo. Please feel free to continue the conversation there! Thanks again!

Add this line below at the top of promise.d.ts to declare the Promise variable will fix the problem:
declare var Promise: PromiseConstructor;

[fairsayan]

Is this an issue related with ionic or angular2? What is the best way to have this fix included in the core (without the necessity to manually add this line everytime I create a new project)?

[MrBokeh]

angular2 module

I also encounter this issue today.
But in addition to the fix mentioned by @MrBokeh in the promise.d.ts file, I also had to add this on top of my gulpfile.js : require('es6-promise').polyfill();

Edit: I forget to mention that I init my project with --sass flag : ionic start ion2 tutorial --v2 --ts --sass

Hi !

I have the same issue, however there is no promise.d.ts file on my side, how is this possible ? :-/
I used the ionic start --v2 --ts command.

My bad, updating promise.d.ts file worked for me. :+1:

Where I should add declare var Promise: PromiseConstructor;?

[fairsayan]

@GaneshPediredla as described by @MrBokeh : at the top of promise.d.ts

[GaneshPediredla]

yes got it. But every project i should do like this. Its bit difficult to for every project. Any otherway to solve this problem permanently?

[veswanthRaju]
