Ionic-app-scripts build fails, ngc failed


Hello everyone! I’m trying to build my project, but all I get is this output… And I declared the SettingsPage component on app.module (declarations and entryComponents).

[11:27:45] ionic-app-scripts 0.0.45
[11:27:45] build prod started …
[11:27:45] clean started …
[11:27:45] clean finished in 9 ms
[11:27:45] copy started …
[11:27:45] ngc started …
[11:27:46] copy finished in 212 ms
[11:27:58] Error: Cannot determine the module for component SettingsPage!
[11:27:58] ngc failed
[11:27:58] ionic-app-script task: “build”

And I don’t understand, sense when I try to build with ‘cordova build android --release’ or run ‘ionic serve’ it goes alright with no errors. I used to build with cordova, but i need the ionic-app-scripts now for performance reasons, and I’m getting this.

my ionic info:

Cordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.3
Ionic CLI Version: 2.1.8
Ionic App Lib Version: 2.1.4
Ionic App Scripts Version: 0.0.46
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Linux 3.16
Node Version: v7.1.0
Xcode version: Not installed


I still haven’t solve this issue, need some help here, guys…


I may have had a similar problem and I never got a satisfactory explanation from the forum, but I had a workaround:
If I change my package.json to have “ionic:build”: “ionic-app-scripts build --dev”, with the --dev flag, I can get my app to run on my android device. It always ran fine with ionic serve.
In my case, the problem may be an external module which declares a “passthrough” export of all classes in 2 subordinate modules. That starts getting deeper than my understanding of typescript and angular2, however.
