Question

由于某些原因，尝试使用extract-text-webpack-plugin构建时此配置失败。我已经尝试使用extract-text-webpack-plugin几天了，并且在尝试输出css时遇到了很多问题。我觉得在按照许多指南并查看了许多SO问题之后我已经正确配置了它，但也许我错过了一些东西..

webpack.config.js

var entry_object = {};
entry_object[build_js_dir + "file.js"] = static_js + 'file.js';
  entry: entry_object,
  output: {
    path: './',
    filename: '[name]',
    chunkFileName: "[id].chunk.js"
  },
  module: {
    loaders: [{
      test: /\.js$/,
      include: path.resolve(__dirname),
      exclude: /node_modules/,
      loader: 'babel-loader',
      query: {
        presets: ['react', 'es2015']
      }
    },
    {
      test: /\.scss$/,
      loader: ExtractTextPlugin.extract("css-loader!sass-loader")
    }
]}
  plugins: [
    new ExtractTextPlugin("[name].css"),
    ]
}

但是当我将它用于scss加载器时，它工作正常：

{
  test: /\.scss$/,
  include: /.scss$/,
  exclude: [
    static_scss,
    static_scss_pdf
  ],
  loaders : [
    'style-loader',
    'css-loader?sourceMap',
    'sass-loader?sourceMap'
  ]
},

OP的问题是意外@（可能附加到@import）。
尝试解析url(./filename.png)

之类的内容时会出现相同的错误消息

ERROR in ./~/jquery-ui/themes/base/images/ui-icons_cc0000_256x240.png
Module parse failed: /myproject/node_modules/jquery-ui/themes/base/images/ui-icons_cc0000_256x240.png Unexpected character '�' (1:0)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected character '�' (1:0)

我需要安装url-loader和file-loader并将它们作为加载器添加到webpack中：

npm install --save url-loader
npm install --save file-loader

webpack.config.js

module: {
    loaders: [
        { test: /\.css$/, loader: "style-loader!css-loader" },
        { test: /\.png$/, loader: "url-loader?limit=100000" }
    ]
}

现在很高兴地介绍这些文件：

  $ webpack
  ...
  [69] ./~/css-loader!./~/jquery-ui/themes/base/tooltip.css 528 bytes {4} [built]
  [70] ./~/css-loader!./~/jquery-ui/themes/base/theme.css 18.7 kB {4} [built]
  [71] ./~/jquery-ui/themes/base/images/ui-icons_444444_256x240.png 5.05 kB {4} [built]
  [72] ./~/jquery-ui/themes/base/images/ui-icons_555555_256x240.png 5.05 kB {4} [built]

在插件之前，您在对象的末尾缺少逗号。它应该是：

]},
  plugins: [
    new ExtractTextPlugin("[name].css"),
    ]
}

我偶然发现了这个问题，因为我和你有着完全相同的问题。如果逗号不是问题，我按照本指南开始工作：http://www.jonathan-petitcolas.com/2015/05/15/howto-setup-webpack-on-es6-react-application-with-sass.html
