Error with ng build --prod

[hassanasad]

With version 1.0.0-beta.12 - when ng build --prod is called it fails to compile saying:

ERROR in Error during template compile of 'CoreModule'
  Function calls are not supported in decorators but 'IntercomModule' was called.

P.S: I use a CoreModule instead of AppModule

It works fine with 1.0.0-beta.11 though

not sure if this is related but seems to be:
angular/angular#14707

also this as well
angular/angular-cli#3854

It seems it might be related indeed @chrishawn. It might also be related to ng-packagr which is now used to output the library. PRs are welcome, I don't think I will be able to get to it until this weekend.

[chrishawn]

i poked around with it for a little while both options didn't seem to fix it, i think one needs to dig deeper, also many people having problems with this.

[KromPass]

I have the same problem.

[scott-wyatt]

Sorry everyone, I've been busy. This error is being caused by ng-packagr, I'll try and get a fix out for this as soon as possible unless someone beats me to it.

[scott-wyatt]

Fixed by #42

[eyalhakim]

@scott-wyatt this reproduces now for me in beta.6

[motcowley]

Also seeing the same problem on 6.0.0-beta.x

[chrishawn]

yeah it definitely seems to be back
