使用webpack和postcss-loader导入字体很棒

我正在尝试更新我的webpack构建以利用postcss和postcss-loader . 但是我在加载字体，图像等时遇到问题 .

例如，试图让字体真棒导入 .

这是我在postcss工作之前的设置：

CSS：

@import "~font-awesome/css/font-awesome.min.css";

webpack.config：

...
  module: {
    rules: [{
      test: /\.css$/,
      use: ExtractTextPlugin.extract({
        fallback: 'style-loader',
        use: 'css-loader'
      })
    },{
      test: /\.(eot|svg|ttf|woff|woff2)$/,
      loader: 'file-loader?name=fonts/[name].[ext]'
    },{
      test: /\.(png|jpg)$/,
      loader: 'file-loader?name=images/[name].[ext]'
    },{
      test: /\.html$/, loader: 'raw-loader'
    }]
  }
  ...

试图转向：

@import 'font-awesome'

webpack w / postcss：

...
  module: {
    rules: [{
      test: /\.css$/,
      use: ExtractTextPlugin.extract({
        fallback: 'style-loader',
        use: [{
          loader: 'css-loader',
          options: {
            importLoaders: 1
          }
        },{
          loader: 'postcss-loader',
          options: {
            ident: 'postcss',
            sourceMap: true,
            plugins: [require('postcss-import')()]
          }
        }]
      })
    },{
      test: /\.(eot|svg|ttf|woff|woff2)$/,
      loader: 'file-loader?name=fonts/[name].[ext]'
    },{
      test: /\.(png|jpg)$/,
      loader: 'file-loader?name=images/[name].[ext]'
    },{
      test: /\.html$/, loader: 'raw-loader'
    }]
  }
  ...

但是，当我这样做时，我得到这样的错误：

./style.css中的错误模块构建失败：ModuleNotFoundError：找不到模块：错误：无法解析'/ test-project / public'中的'../fonts/fontawesome-webfont.eot'

我也尝试过其他一些库（即bootstrap，leaflet），并遇到了同样的问题 .

webpack postcss postcss-loader postcss-import

    看来 css-loader 无法解析 font-awesome/fonts 目录的相对url路径 .

    你需要在 css-loader 选项中使用alias .

    use: [{
  loader: 'css-loader',
  options: {
    importLoaders: 1,
    alias: {
      "../fonts": "font-awesome/fonts"
    }
  }
}

    我在一个示例项目中测试了它，它似乎成功编译 .

    如果您还使用了使用 ../fonts 相对路径的项目，则可能还需要更具体的别名 .

    这个webpack配置解决了我的问题：

    const rules = [{
  test: /\.css$/,
  use: [
    'style-loader',
    {
      loader: 'css-loader',
      options: {
        importLoaders: 1,
        sourceMap: true,
      }
    },
   'resolve-url-loader',
    {
      loader: 'postcss-loader',
      options: {
        sourceMap: true,
        ident: 'postcss',
        plugins: () => [],
      }
    }
  ]
}, {
  test: /\.(png|woff|woff2|eot|ttf|svg)$/,
  loader: 'url-loader?limit=100000',
}]
