通过相对路径包含图像的正确方法

我已经更新了laravel-mix到版本4.0.12,面对*.scss在我使用相对路径包含背景图像的线上的破坏构建

我有一个下一个文件结构

resources/
|-assets/
||-img/
|||-background.png
||-sass/
|||-footer.scss

我在footer.scss中的代码是下一个

.footer {
  background-image: url(../img/background.png)
}

我的webpack.mix.js是下一个

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

const resourcesAssets = 'resources/assets/';
const dest = 'public/assets/';

mix
  .copy(`${resourcesAssets}images`, `${dest}images`, false)
  .sass(`${resourcesAssets}scss/footer.scss`, `${dest}css`);

在筹备期间,npm run prod我得到了

Module build failed (from ./node_modules/css-loader/index.js):
ModuleBuildError: Module build failed (from ./node_modules/resolve-url-loader/index.js):
Error: resolve-url-loader: CSS error

        error  in ./resources/assets/sass/footer.scss

我该如何解决这个问题？

这个问题太新了"resolve-url-loader": "^3.0.0".

在"laravel-mix": "~3"不久前安装了一个中间版本后,它被添加到package.json中.

删除它并重新运行构建有助于我解决问题."resolve-url-loader": "2.3.1"运行后加入laravel-mix npm run prod.
