css - SASS compass 编译器在多重赋值 @each 循环中窒息

Question

以下是来自 SASS documentation 的示例:

@each $animal, $color, $cursor in (puma, black, default),
    (sea-slug, blue, pointer),
    (egret, white, move) {
  .#{$animal}-icon {
     background-image: url('/images/#{$animal}.png');
     border: 2px solid $color;
     cursor: $cursor;
   }
}

出于某种原因，它会抛出以下错误:

error sass/screen.scss (Line 8: Invalid CSS after " @each $animal": expected "in", was ", $color, $curs...")

我尝试卸载并重新安装 ruby​​/sass/compass 无济于事。是什么赋予了？以下是我的版本:

• SASS 3.2.19
• compass 0.12.5

Answer 1

看起来多重赋值是 SASS 3.3 的特性。也许this会有帮助。
