RAILS_ENV=production rake assets:precompile fails locally

Thanks for open sourcing this project.

I spent some time debugging this issue. The culprit appears to be the removal of image-url in node-sass/libsass lately:

sass/node-sass#965

The output of gulp build creates a global.css with image-url still in it:

body {
 58   background: #dd3435 image-url("gulp.png");
 59   font-family: sans-serif; }

Oh yeah, that's been removed. I need to replace those. Thanks. Feel free to open a pull request if you get to it before me!
