Cryptic exception when there is an error in ionic.config.js (ionic2)

[dupski]

Hi Guys

Would it be possible to improve the error reported when there is a syntax error in your ionic.config.js ?

The current exception doesn't reference the file at all:

$ ionic run android --live-reload

SyntaxError: Unexpected identifier

Yeah webpack config errors are similarly unhelpful I believe, thanks for the issue, we'll be looking into this.

Digging into this a bit more, I believe this is a problem on node's end: nodejs/node#2762, nodejs/node#3411, nodejs/node#3784.

If you'd like verbose errors, it appears node v0.12 still contains the "arrow message" with helpful line number information.

Going to close this as not an Ionic issue, but feel free to comment on here if you're still having issues, thanks!

Thanks Tim

For anyone else that comes across this issue, it is fixed in Node 4.2.5 (I am on 4.2.4), and Node 5.2.0!

Cheers
