error TS2304: Build:Cannot find name 'Iterable' after upgrading to Angular 4 : <p>I am using Typescript 2.4.1 and have upgraded many packages in my project. Among them I upgraded Angular from 2 to 4.3.1.
After many corrections in @types packages, the errors I am left with are:</p>

<pre><code>\node_modules\@types\jquery\index.d.ts(2955,63): error TS2304: Build:Cannot find name 'Iterable'.

<p>I have found many similar questions and answers and the prevailing solution is to target "es2015" and/or add lib: ["dom", "es2015", "es2015.iterable"].
I have tried all those and more but am still left with the same 'Iterable' error.</p>

<p>My updated tsconfig.json is thus:</p>

<p>How can it be that "iterable" is not found after all those lib inclusions?
The Typescript compiler does not ignore my tsconfig.json as changing some option gives various outputs, but none without errors.</p>

<p>My environment is Visual Studio 2015 update 3 with Typescript Tools 2.4.1.
I am using npn @types (no typings).
Verbose compilation output shows that Visual Studio effectively uses the 2.4.1 version.</p>

<p>And the most bizarre thing is that compiling using gulp gives no error using the same Typescript version and tsconfig.</p>
