The issue was in the angular2-text-mask lib. Not sure why. Perhaps because of it has angular 2 dependencies. Will have to fork it. Anyway, thank you for the great tool.

@sshraki I mean ng-packagr is a great tool. To resolve the issue you should add all your external dependencies to lib.externals in ng-package.json. Check each of them in your package.json one by one to determine which one causes the issue. hope it helps.
