When you updated your project from an earlier version of the framework I would suggest to check if you performed the update properly. If you missed something by the update, it might result in such problems. Check out the following post for more details (and also this Github comment ) :
I believe that your problem might be caused by the following line in your app.ts:
import 'es6-shim';
You need to remove this - check out the guide for updating to beta.6 .
I would also recommend you to use Node v4/v5 but not v6 because it’s not supported yet:

#### Short description of the problem:
When there's an error in the code _(Java… Script/TypeScript/HTML)_ it is not displayed in the console.
#### What behavior are you expecting?
A error should be displayed in the console to indicate that something is wrong with details about the cause.
**Steps to reproduce:**
1. Make sure to test on **Mac OS X El Capitan**.
2. Start a new project: `ionic start TestAppJS blank --v2`.
3. Replace the content of `home.js` with the code below.
4. Run `ionic serve`.
5. Observe that no error is shown in the console.
``` js
// NOTE: Intentionally not importing Storage so that an exception is thrown.
import {Page, NavController, SqlStorage} from 'ionic-angular';
@Page({
templateUrl: 'build/pages/home/home.html'
})
export class HomePage {
static get parameters() {
return [[NavController]];
}
constructor(nav) {
this.db = new Storage(SqlStorage);
}
}
```
