Ionic serve not running gulp task

Ionic Framework ionic-v3
1

I installed RC0 and now we decided to rollback to Beta11. The project is working, but the gulp tasks do not run anymore when running ionic serve. I need to run gulp build for every change I make, which takes me a lot of time.

Has someone faced this?

Do you have tasks defined in your package.json? If so, they will take priority over gulp

This is it, thanks @mhartington
