node_modules中的webpack 4映像：找不到模块

Question

问题

我使用webpack 4将scs编译为css，并使用MiniCssExtractPlugin将css保存到另一个文件中。问题是，我没有设法加载图像和字体，这些图像和字体是通过scss文件内部的url（）包含的。运行开发或生产之间也没有区别。 Scss编译完美，没有任何问题。同样，scss-loader可以从node_modules加载.scss文件。 为什么会发生此错误，我该如何解决？

运行npm时的错误消息

ERROR in ./ui/index.scss (./node_modules/css-loader!./node_modules/sass-loader/lib/loader.js!./ui/index.scss)

还有更多，但都具有相同的错误，只是文件名发生了更改。

const path = require('path');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

您需要向构建中添加resolve-url-loader，如下所示：

{
    test: /\.scss$/,
    use: [
        MiniCssExtractPlugin.loader,
        "css-loader",
        "resolve-url-loader",
        "sass-loader?sourceMap"
    ]
}

resolve-url-loader正在基于导入资产的原始文件来解析资产的路径。

我在本地尝试过，构建现在正在通过:)干杯！
