Fatal error: Call to undefined method SassBoolean

[yumyo]

After some configuration attempts all the compiling error seem solved, but now I'm facing the following
Fatal error: Call to undefined method SassBoolean::length() in ../wp-content/plugins/wp-sass/phpsass/script/SassScriptFunctions.php on line 874 cache and debug are set to true.

Any help will be greatly appreciated

line 874 of SassScriptFunctions.php "List Functions - taken mostly from Compass" ... so may the problem be the way I import compass? I'm using 'load_paths' => array("compass", "partials/susy", "partials/modular-scale") in wp-sass.php and @import "compass"; in my .scss file

I'm a little confused, have you modified wp-sass.php?

[yumyo]

yep, isn't it the way to use compass? Now switched back to the original wp-sass.php and still getting the same error.

[roborourke]

No you should need to modify wp-sass at all. Can you not just enqueue or @import the compass dependencies?

[yumyo]

Ok perfect. I've found that what is causing the problem is trying to @import susy. Looking at http://susy.oddbird.net/guides/upgrade-1-0/ seems that the minimum requirement for susy to work is Sass 3.2.0.
Which probably it is mainly used by the at-breakpoint mixins.

Aha! Thanks for finding that out. I'll see if there's an update for phpsass, until then though susy will have to wait :/

[roborourke]

@yumyo hey! I've just rolled out the updated phpsass submodule, can you try this again?
