Cannot import vertical_rhythm when import once is active in 1.0

[kylemacfarlane]

I started a new project with the 1.0 alpha and for some reason I'm not able to import the vertical_rhythm module.

I've reduced it down to config.rb:

require 'compass/import-once/activate'
http_path = "/"
css_dir = "css"
sass_dir = "sass"
images_dir = "img"
javascripts_dir = "js"

And in my style.scss I only have:

@import "compass/typography/vertical_rhythm";

When using compass watch it throws the following:

Errno::ENOENT on line ["346"] of C: No such file or directory - C:/Users/KyleMac/Documents/compass-test/.sass-cache/75fcaf1b4852ceb732871195e41567cc2a7d8997/C%058%092Ruby193%092lib%092ruby%092gems%0921.9.1%092gems%092compass-core-1.0.0.alpha.19%092stylesheets%092compass%092_support.scssc20140323-18940-1tri2kd.lock

I found that removing require 'compass/import-once/activate' seems to bypass the error.

I get this problem too, anyone found a fix? I want to use the 'import-once' as its seems quite practical, but I cannot use it when I call anything related to compass e.g.

@import "compass/css3"; @import "compass/typography";

However, import-once works fine with anything else e.g. @import "breakpoint";

A patch would be helpful, I can try to get a windows machine working for testing this. But it's not top priority since you can simply comment out that require for now.
