Sass::SyntaxError: Undefined mixin 'trailer'.

[maxim]

Trying to compile nanoc project with compass+susy I keep getting "Sass::SyntaxError: Undefined mixin 'trailer'." when trying to compile default templates that come with susy. Susy seems to be imported fine, but the trailer thing is not.

Just found out it doesn't see a bunch of susy mixins... And doesn't complain on import still.

Are you sure that any part of susy is being imported properly? Do you have "require 'susy'" in your congig.rb file? I don't know anything about nanoc, but removing the 'require' line from config.rb replicates your error.

This was my issue. Asked Chris Eppstein, turns out didn't even have require 'susy' in my config.rb.

I just updated Compass to 0.11.1 with a simple gem update and now I am getting the following errors on compile:

WARNING: The 'susy/susy' import is deprecated. Instead: simply import 'susy'.
        on line 1 of /Library/Ruby/Gems/1.8/gems/compass-susy-plugin-0.9/lib/../sass/susy/_susy.scss
        from line 20 of /Users/stephencarr/Dropbox/Sites/nslocal/nslocal.com/src/_base.scss
        from line 10 of /Users/stephencarr/Dropbox/Sites/nslocal/nslocal.com/src/_defaults.scss
        from line 5 of /Users/stephencarr/Dropbox/Sites/nslocal/nslocal.com/src/screen.scss
    error src/screen.scss (Line 81: Undefined mixin 'trailer'.)

So, I changed the import to simply say 'susy' but it still complains about (Line 81: Undefined mixin 'trailer'.).

I definitely have the require 'susy' in my config :(

Yep. The 'trailer' mixin comes from Compass, not Susy. So you're getting Susy just fine. Add a compass import and you'll be all set:

@import "compass";

Cheers!
