我有一个非常基本的Vue应用程序，我想使用laravel-mix进行编译，但是我一直遇到错误。
我的webpack.mix.js就像这样：我想将已编译的js和css文件放入不同的文件夹
const mix = require('laravel-mix');
mix.js('src/main.js', 'out/js').
styles('src/assets/theme.css', 'out/css');
我的package.json看起来像这样，错误是当我尝试运行npm run dev时。我在npm运行dev之前先进行过npm安装

，错误看起来像这样。我不知道为什么会收到mix.combine（）错误。
AssertionError [ERR_ASSERTION]: mix.combine() requires a full output file path as the second argument.
