Re-importing @import files

How can I trigger the re-importation of @import files? I make changes to them, but those changes don’t ever appear in the compiled *.css file. The only solution I have found is to delete the *.scss file from the server, upload a fresh *.css file, and re-upload my *.scss file, but this is too cumbersome to do with the regularity with which I update the @import fies.
