Always get grunt error

[rugk]

I've followed this instructions but actually it always ends up with an error:

grunt-exec@0.4.6 requires a peer of grunt@~0.4 but none was installed.

and when running grunt:

>> Error: File to import not found or unreadable: foundation/functions
>>        Parent style sheet: /var/www/.../istlsfastyet/scss/_settings.scss
>>         on line 9 of scss/_settings.scss
>> >> @import "foundation/functions";
>>    ^
Warning:  Use --force to continue.

Aborted due to warnings.

Running on Debian
NodeJS v5

Try npm install --global gulp before you compile. The site is based on WSK: https://github.com/google/web-starter-kit/blob/v0.6.1/docs/install.md

Still get the same error. Do I need to clone WSK before?

$> npm install -g bower
$> bower install
$> npm install grunt
$> grunt install

Should do the trick.
