从节点js模块导入css

我正在使用webpack，我可以“导入”css文件而不会出错，但css不会在最终产品中导出

网页摘要：

 module: {
    loaders: [
      {test: /\.css$/,loader: 'css-loader'},
      {test: /\.scss$/,loader: ExtractTextPlugin.extract('css-loader!sass-loader')},
      {test: /\.js$/, loader: 'babel-loader', include},
      {test: /\.json$/, loader: 'json', include},
      {test: /\.jpe?g$|\.gif$|\.png$/i, loader: "file-loader" },
    ]
  },

运行：

代码：

我没有对css文件使用提取

{test: /\.css$/,loader: 'css-loader'},

应该是：

{test: /\.css$/,loader: ExtractTextPlugin.extract('css-loader')},

除了您的答案之外，您还需要将ExtractTextPlugin添加到

插件

数组中，以定义导出提取的CSS的位置

module: {
  loaders: [
    {test: /\.css$/,loader: ExtractTextPlugin.extract('css-loader')},
    {test: /\.scss$/,loader: ExtractTextPlugin.extract('css-loader!sass-loader')},
    {test: /\.js$/, loader: 'babel-loader', include},
    {test: /\.json$/, loader: 'json', include},
    {test: /\.jpe?g$|\.gif$|\.png$/i, loader: "file-loader" },
  ]
  plugins: [
    new ExtractTextPlugin({ filename: 'style.css' }),
  ],
},

{test: /\.css$/,loader: ExtractTextPlugin.extract('css-loader')},

module: {
  loaders: [
    {test: /\.css$/,loader: ExtractTextPlugin.extract('css-loader')},
    {test: /\.scss$/,loader: ExtractTextPlugin.extract('css-loader!sass-loader')},
    {test: /\.js$/, loader: 'babel-loader', include},
    {test: /\.json$/, loader: 'json', include},
    {test: /\.jpe?g$|\.gif$|\.png$/i, loader: "file-loader" },
  ]
  plugins: [
    new ExtractTextPlugin({ filename: 'style.css' }),
  ],
},
