compass生成精灵图出错

Question

webstorm中利用compass生成精灵图

@import "compass/utilities/sprites";
@import "share/*.png";
@include all-share-sprites;

其中，第二步@import "share/*.png";报错
错误信息“error sass/stylesheet.scss (Line 30 of share/*.png: Invalid CSS after " $share-little ": expected ":", was "plane-position:...")”
