Message "Failed to instantiate module growlNotifications..." appear on production env

I am current using mean.io as development framework of my application and have been using growlNotifications plug-in for certain time and it works perfect on both server and client side.

while after some coding commit (does not affect the plug-in), the following error appear on the production server:

Uncaught Error: [$injector:modulerr] Failed to instantiate module acleague due to:
Error: [$injector:modulerr] Failed to instantiate module growlNotifications due to:
Error: [$injector:nomod] Module 'growlNotifications' is not available! You either...<omitted>...3) 

but it won't have any problem running on local. I ensure that the bower install work perfectly on production server and i did nth in the grunt file.

Could anyone help me or even give me some hints to solve this problem? Thanks a lot!
