Susy 2.0.0.alpha.6 - Undefined mixins'at-breakpoint','remove-nth-omega'

使用:

susy(2.0.0.alpha.6)

sass(3.3.0.rc.2)

指南针(1.0.0.alpha.17)

使用以下SCSS:

$susy: (
    columns: 12,
    column-width: 5em,
    gutter-width: 1em,
    gutter-position: after,
    grid-padding: gutter-width,
);

$small: 36em;
$medium: 50em;
$large: 65em;

.hlt-container{
    @include at-breakpoint($small) {
        @include span(6);
        @include nth-omega(2n);
        margin-bottom: gutter(12);
    }

    @include at-breakpoint($small $large) {
        &:last-child:nth-child(odd){
            float: none;
            clear: both;
            margin-right: auto;
            margin-left: auto;
        }
    }

    @include at-breakpoint($large) {
        @include span(4);
        @include remove-nth-omega(2n,12);
        @include nth-omega(3n);
        margin-bottom: 0;
    }
}

我首先得到错误: error source/scss/style.scss (Line 10 of source/scss/01-molecules/02-blocks/_00-highlight-block.scss: Undefined mixin 'at-breakpoint'.)

如果我删除了at-breakpoint样式,它会继续运行并再次阻塞remove-nth-omega: error source/scss/style.scss (Line 26 of source/scss/01-molecules/02-blocks/_00-highlight-block.scss: Undefined mixin 'remove-nth-omega'.)

我已经通过文档搜索和Google搜索一切我能想到的,但似乎无法找到问题,如可能at-breakpoint和remove-nth-omega与与Susy下被弃用.

编辑:

如果我改回来

指南针(0.12.2)

sass(3.2.12)

苏西(1.0.9)

(谢天谢地,RVM和gemsets)

并恢复.scss以反映较旧的Susy语法:

$columns: 12;
$column-width: 5em;
$gutter-width: 1em;
$gutter-position: after;
$grid-padding: $gutter-width;

$small: 36em;
$medium: 50em;
$large: 65em;

.hlt-container{
    @include at-breakpoint($small) {
        @include span-columns(6,12);
        @include nth-omega(2n);
        margin-bottom: gutter(12);
    }

    @include at-breakpoint($small $large) {
        &:last-child:nth-child(odd){
            float: none;
            clear: both;
            margin-right: auto;
            margin-left: auto;
        }
    }

    @include at-breakpoint($large) {
        @include span-columns(4,12);
        @include remove-nth-omega(2n);
        @include nth-omega(3n);
        margin-bottom: 0;
    }
}

一切正常.
