带有sass-loader和resolve-url-loader的Webpack 4-找不到图像路径

此处可复制的设置最少:https://github.com/jamesopti/webpack_playground/tree/resolve_url_loader_issue

我正在尝试使用resolve-url-loader向我的scss url()图像路径添加哈希名称，但是我花了一点时间才能使其与Webpack 4一起使用。
我在/static/img/**中有一堆图像，这些图像在我的SCSS中被引用为:

span.arrow {
  background: url(/static/img/audiences.png);
}

最终以完全相同的结果出现在我的CSS中(resolve-url-loader无法找到它们)

当我通过webpack运行以下配置时，我看到resolve loader正在找到正确的url()及其路径，但是 Debug模式会显示NOT FOUND。

resolve-url-loader: /static/img/audiences.png
  /Users/usr1/webpack_playground/src
  /Users/usr1/webpack_playground/static/img
  NOT FOUND

是否有一些输出配置那是不正确的？我尝试了各种设置组合，但无济于事:

  loader: 'resolve-url-loader',
  options: {
    debug: true,
    root: path.join(__dirname, './static/img'),
    includeRoot: true,
    absolute: true,
  },

我的最终目标是使文件加载器将其转换为/dist哈希版本:

span.arrow {
  background: url(/static/img/audiences-dhsye47djs82kdhe6.png);
}

//Webpack规则配置

rules: [
      {
        test: /\.(png|jpg|gif)$/,
        include: [
          path.resolve(__dirname, './static/img'),
        ],
        use: {
          loader: 'file-loader',
          options: {
            name: '[name]-[hash].[ext]',
          },
        },
      },
      {
        test: /\.svg$/,
        use: {
          loader: 'svg-inline-loader',
          options: {
            name: '[name]-[hash].[ext]',
          },
        },
      },
      { test: /\/src\/js\/(?:.*)\.css$/, use: [ { loader: 'style-loader' }, { loader: 'css-loader' } ] },
      {
        test: [/\.scss$/, /\.sass$/],
        use: [
          MiniCssExtractPlugin.loader,
          {
            loader: 'css-loader',
            options: {
              sourceMap: true,
            },
          },
          {
            loader: 'resolve-url-loader',
            options: {
              debug: true,
              root: './static/img',
              includeRoot: true,
            },
          },
          {
            loader: 'sass-loader',
            options: {
              outputStyle: 'compressed',
              sourceMap: true,
              includePaths: [
                './src'
              ],
            },
          },
        ],
      },
]

最佳答案

事实证明，我所需要做的就是file-loader来完成我想要的事情。

当任何css/sass/style加载器遇到图像(与我指定的文件扩展名匹配)时，其通过file-loader处理，将图像复制到指定的命名格式指定的输出目录，并返回sass加载器的名称用作文件名。

rules: [
  {
    test: /\.(png|jpg|gif|svg)$/,
    exclude: [
      path.resolve(__dirname, './node_modules'),
    ],
    use: {
      loader: 'file-loader',
      options: {
        name: '[path][name]-[hash].[ext]',
        outputPath: '../',
        publicPath: '/dist',
      },
    },
  },
  {
    test: /\.svg$/,
    include: [
      path.resolve(__dirname, './node_modules'),
    ],
    use: {
      loader: 'svg-inline-loader',
      options: {
        name: '[name]-[hash].[ext]',
      },
    },
  },
  { test: /\/src\/js\/(?:.*)\.css$/, use: [ { loader: 'style-loader' }, { loader: 'css-loader' } ] },
  {
    test: [/\.scss$/, /\.sass$/],
    use: [
      MiniCssExtractPlugin.loader,
