Error: File to import not found or unreadable: variables.

Hi,

I've had a strange problem. When starting a local server, I run into this error message:

> The Broccoli Plugin: [BroccoliMergeTrees] failed with:
Error: File to import not found or unreadable: variables.
Parent style sheet: /Users/jonmcewen/Desktop/mySite/tmp/sass_compiler-input_base_path-1xeuikfD.tmp/addon.scss
at options.error

In my app.scss file, I was using a few variables. I was able to keep the error from occurring by deleting the variables and saving. The server would start just fine. Then I'd go back and add the variables and save again -- no problems.

The issue only comes up when initially starting the server.

I've since added ember paper. The same issue persisted. I used the same solution. Now when I'm running ember build --prod, I'm seeing the same error.

Any help is much appreciated.

Cheers,
Jon
