保存到scss文件会自动更新css文件吗？

I just started working with scss a few days ago (with Webstorm), and it seem to auto generate/update the css file after saving the scss file. Unfortunately, when I save the scss file now, no changes are made to the css file. I was working on these files from a different location, so I am guessing that the Webstorm settings might be different. I thought file watchers might have something to do with it, but I am not sure what goes in the program field. I really have no idea why this is happening.I just started working with scss a few days ago
