Sprites error after updating compass

[Gary Clarke]

I updated ruby and had to re-install gems:

gem install sass --pre

gem install compass --pre

By selective removal of sass code I tracked down a watch error that is now occurring due to the following statement:

@import "../shared/images/icon/*.png";

The error is "TypeError on line ["27"] of C: can't convert Array into String".

This same code was working before the re-install. Here's the first part of the stack trace:

  C:/Ruby193/lib/ruby/gems/1.9.1/gems/compass-0.12.rc.1/lib/compass/sass_extensions/sprites/image_methods.rb:27:in `block in sprite_names'

  C:/Ruby193/lib/ruby/gems/1.9.1/gems/compass-0.12.rc.1/lib/compass/sass_extensions/sprites/image_methods.rb:27:in `map'

  C:/Ruby193/lib/ruby/gems/1.9.1/gems/sass-3.2.0.alpha.64/lib/sass/script/funcall.rb:88:in `_perform'

I reviewed the sprite tutorial at http://beta.compass-style.org/help/tutorials/spriting/, but as far as I can tell the usage hasn't changed.

Any thoughts on what might be happening?

Thanks for your help,

The import is relative to your images directory. Please just use:

@import "icon/*.png";

Chris, 

The path "../shared/images/icon" is relative the the compass images directory. My raw image assets are in a different folder because I'm sharing some files across projects:

  /images -> this is the compass project images folder

  /shared/images/icon -> this is what I'm importing

Any thoughts?

Regards,

Gary

In 0.12, you should add the shared folder to your images sprite path in your config:

sprite_load_path << "/shared/images"

I know this is a relatively old thread but just in case someone is having the same problem and finds this thread, this worked perfectly for me.
