在sass编译中，@use被忽略了

Question

我使用Laravel-mix来编译我的assets与webpack.

当调用 npm run dev 我收到这个警告。

  (Emitted value instead of an instance of Error)   resolve-url-loader cannot operate: CSS error
  /home/adam/www/homestead/memberportal/resources/assets/css/listing/funny.scss:2:264: missing '{'
  at error (/home/adam/www/homestead/memberportal/node_modules/css/lib/parse/index.js:62:15)

 @ ./resources/assets/css/listing/funny.scss 4:14-280
 @ multi ./node_modules/laravel-mix/src/builder/mock-entry.js ./resources/assets/css/listing/funny.scss

似乎sass编译器无法工作.

这是我的 webpack.mix.js:

let mix = require('laravel-mix');

mix.sass('resources/assets/css/listing/funny.scss', 'public/css/');

这就是内容。funny.scss:

@use 'xy';

这就是内容 _xy.scss:

h1{
  color: red;
}

这是汇编的结果。funny.css

@use "xy";

为什么sasss编译在这里不能用?

不知怎的, 我的 package.json 丢失了依赖关系。一定是在分支过程中丢失了它。添加了 sass, sass-loader 和 resolve-url-loader 为我解决了这个问题。
