compass-mixins 插件无法在 Angular2 的浏览器中正确翻译背景图像属性

我正在使用 compass-sass-mixins 版本 0.12.7。我的 angular 版本是 2.4.3 我的 background-image 属性在我构建代码时没有显示在浏览器上。

我的background-image财产是我的global.scss文件如下：

    body{
  background-color: rgba(44,22,78,1);
  @include filter-gradient($clr-purple, $clr-orange, vertical);
  @include background-image(linear-gradient(top, rgba(44,22,78,1) 0%, rgba(164,64,131,1) 50%, rgba(164,64,131,1) 50%, rgba(255,126,90,1) 100%));
  font-family: $font-regular;
  letter-spacing: 0.7px/$base-font-size+rem;
}

当我使用 构建代码时ng build，我收到以下警告：

PIE does not support background-image. Use @include background(linear-gradient(top, #2c164e 0%, #a44083 50%, #a44083 50%, #ff7e5a 100%)) instead.
Backtrace:
    node_modules/compass-sass-mixins/lib/compass/css3/_images.sass:48, in mixin `background-image`
    src/_global.scss:18

当我在 global.scss 中添加上面建议的行而不是原始行时，警告消失了，但更改仍然没有反映在我的浏览器中。

这个指南针混合是版本问题吗？

无法在此处复制，因为它目前是我的生产版本的一部分。任何人都可以帮忙吗？
