@linchanglin thanks a lot for pointing this out!
It seems it's an issue regarding the new angular version, as this project was just updated to use angular 5.
This seems to be related: ionic-team/ionic-app-scripts#1309

I'll take a further look later on, but if you downgrade to ionic 3.7 (or just angular to 4.4) I believe it will work without issues.
Please let me know if you move on with a solution for this also.

Thanks!

@yannbf thanks a lot for helping me.
as you said, it is seems to be the problem of "@ionic/app-scripts", I figured out by downgrading angular to 4.1.3 and "@ionic/app-scripts": "^2.1.4", and it works fine.
Thanks again for your help！

@linchanglin I have effectively fixed all issues regarding the newest Angular, so you can use the current version without any issues.
