问题
I have noticed that with the latest rails and sprockets versions (3.2.1 & 2.2.0) there seems to be a problem when the erb file extension is added to a sass partial.
e.g. if somestylefilename.css.sass is renamed to somestylefilename.css.sass.erb and the file contains a declaration of a sass variable that uses erb, vis:-
$background-colour: <%= '#fff' %>;
all is ok.
However if a sass partial is renamed from say _sharedpartial.css.sass to _sharedpartial.css.sass.erb then the same variable declaration is not recognised.
I am not sure if this is the right forum to report this behaviour or if it is a sass, rails or sprockets problem.
P.S. I know that the asset pipeline targets efficiency through pre-compiled assets, but I am trying to write a theeme controller that is capable of selecting the default colour/layout scheme for a site which will subsequently form the default pre-compiled css asset in production.
Best regards,
John Leake

This is a sass-rails error, as discussed here.
I had the same question and found out that the solution is by installing sass-rais-path.
This gets Rails to work SASS + ERB as expected.

This will sound a bit ridiculous, but have you tried to remove the .erb extension?
Normally you don't have to use it, even if you use erb tags.
