Repro steps.

Was this an app that wasn’t created using the CLI? What change did you do on your code? etc.

First it wasn’t working on my already existing project. I tried it with a test-project created with ng new, but still the same error.

The log given by the failure.

Normally this include a stack trace and some more information.

events.js:160
       throw er; // Unhandled 'error' event
       ^
