error TS2304: Build:Cannot find name 'Iterable' after upgrading to Angular 4

'Iterable' is defined in the typings file for node. Installing file that solved the problem for me (node_modules/@types/node/index.d.ts).

npm install @types/node --save-dev

This looks very much what is described here:

https://github.com/DefinitelyTyped/DefinitelyTyped/issues/16939

So either try using

"target": "es6"

as described there - or what works for us:

"target": "es5",
"lib": ["es2016","dom"]
