Ok, I want to give a try to the new FoundationPress 2!! But it seems on my Mac (with El Capitan, should I remove integrity system check?) I can't install it...
Here is the error at the end of the installation (same in the log):

I'm very bad with scripting so my only help here is to try to give you as much information as I can! :)

I also have an 'Error: Cannot find module 'abbrev' while the npm install.
I also try to let the package in a FoundationPress folder, change nothing...

Update Node and try again.

Oh thanks for the suggestion! I update npm but not Node...
Waou, now it's really fast! Also did 'npm rebuild node-sass' after upgrading Node.
Everything seems to be fine now! :)
