Laravel Mix的SourceMap错误中没有“ xxx.scss”

Question

我正在关注Laravel文档，并具有以下文件结构：

在app.scss中，我有：

@import 'style12';
.real-demo{

}

以及在style12.scss中我尝试导入的一些CSS代码。

运行npm run dev时出现以下错误：

Module build failed: Error: "../../resources/assets/sass/style12.scss" is not in the SourceMap.

    at C:\Users\mixei\Desktop\Projects\westcredit\node_modules\postcss\lib\lazy-result.js:231:27

这也是我的webpack.mix.js：

const { mix } = require('laravel-mix');

mix.options({
    processCssUrls: false
});

mix.js('resources/assets/js/app.js', 'public/js')
    .sass('resources/assets/sass/app.scss', 'public/css');

任何帮助将不胜感激，谢谢！
