I have an application which I'm trying to compile using AoT. When I build the application I'm getting the following error:

C:\test\node_modules\@angular\compiler-cli\src\diagnostics\expression_diagnostics.js:14

extendStatics(d, b);

^ TypeError: Object prototype may only be an Object or null: undefined

I know there are certain things that work with JIT compilation that don't with AoT, so my suspicion is I might have something in my code might not work with AoT. Any idea what could be the cause of this error please?

Angular and TypeScript Version

Angular Version: 4.0.1
Angular Compiler CLI: 4.2.5

Could please post which versions of angular and typescript you are using? – Franziskus Karsunke Jul 08 '17 at 13:24
Sure thing, I updated the question – Daniel Grima Jul 08 '17 at 13:27

Okay so I realised that the @angular packages should be the same versions, so I'm updating all of them. I think it should solve the issue – Daniel Grima Jul 08 '17 at 14:13
