Build Failed in Ionic Pro, fine in local

Hi All,

Can anyone help me? my code work fine in local, but I got build failed in Ionic Pro. This is the error :

npm ERR! No valid versions available for pinkie-promise

npm install --quiet --no-optional failed
Running after script...
$ run "clean-up"
ERROR: Job failed: exit status 1

Thank you for your help

What I understand the problem is in NPM registry at NPM. There are several nmp packages missing in nmp registry. They are working on the issue at NPM.
