如何在Laravel 5.3中编译使用指南针的scss文件？

Question

这是Laravel 5.3的gulpfile.js，

var elixir = require('laravel-elixir');

require('laravel-elixir-vue');

elixir(function(mix) {
    mix.sass('app.scss')
       .webpack('app.js');
});

它可以编译scss和js文件，但是，如果scss文件使用指南针，如何编译它？

我尝试了“laravel-elixir-sass-compass”：“^ 0.5.0”，但无法成功安装。

我该怎么办？
