关于纯2.0网格媒体的困惑

根据官方整洁的文件,我应该要使用 gird-media 根据媒体查询更改我的布局。但当我尝试运行示例代码时,会出现以下错误:

@include grid-media($custom-neat-grid, $custom-neat-grid-2){
      ^
  Wrong number of arguments (2 for 1) for `grid-media'

我有一个简单的angular cli项目,包含以下文件:

样式.scss

@import "../bourbon/bourbon";
@import "../neat/neat";

$custom-neat-grid: (
    columns: 12,
    gutter: 50px,
    media: "screen and (max-width: 999px)",
);

$custom-neat-grid-2: (
    columns: 12,
    gutter: 70px,
    media: 1000px,
);

.element {
    @include grid-column(3);

    @include grid-media($custom-neat-grid, $custom-neat-grid-2){
        @include grid-column(6);
      }
}

app.component.html软件

<div class="container">
    <div class="row">
        <div class="element">
            <pre>test</pre>
        </div>
    </div>
</div>

我不知道我做错了什么?
