Node.js Question

Angular2 build errors - cannot find types

I'm having some problems with Typings. When I run

npm start
I get the following errors:

> tsc && concurrently "npm run tscw" "npm run lite"

Others have had this problem over the past months but none of those fixes have worked for me.

Any ideas? (Angular 2)

Answer

If you use --target=es5, you will need to add a line somewhere in your application (for example, at the top of the .ts file where you call bootstrap):

<reference path="node_modules/angular2/typings/browser.d.ts"/>

see this post: Angular 2 typescript can't find names

I personally switched to ES6 which works perfectly fine so far. I also recommend to do the 5min QuickStart and the tutorial series for Angular2 since you could use it as stable Skeleton for further projects: https://angular.io/docs/js/latest/quickstart.html

Good Luck
