Cannot find module 'imagemin-gifsicle'

[albertpeiro]

AngularJS + Yeoman. Trying to build in a Heroku instance it fails. I've tried with node versions 0.10.32, 0.10.31, 0.10.30. None of them work, always the same issue. On the heroku instance I run a postinstall npm -v and I get:

npm cache clean && npm -v && bower install
1.4.21

The error:

Loading "imagemin.js" tasks...�[31mERROR�[39m
[31m>> �[39mError: Cannot find module 'imagemin-gifsicle'

Please point me in the right direction I've researched all issues opened and none of the solutions given work for now. I don't know what to do.

My package.json has:
