Ho appena installato compass seguendo la guida al seguente link:  
[http://compass-style.org/help/](http://compass-style.org/help/)

ma quando faccio per testarlo: aggiungendo un border-radius nel foglio  
di  
stile della mia home mi restituisce l’errore _Undefined mixin  
‘border-radius’_

cosa sto sbagliando? O.o

Ciao Luca, devi importare i mixin prima di poterli usare.

Ad esempio:

@import “compass/css3/border-radius”;

.button {  
@include border-radius;  
}

Ciao

googlando ho scoperto questa cosa:  
[http://jalada.co.uk/2011/10/16/using-compass-with-rails-3-1-final-and-no-hacks.html](http://jalada.co.uk/2011/10/16/using-compass-with-rails-3-1-final-and-no-hacks.html)

Io ho Rails 3.1 e a quanto pare la versione 0.11 di compass non  
funzionante, va installata nel caso la 0.12.alpha :S
