我的 webpack 加载器数组中有这个加载器：

{ test: /\.scss$/, exclude: /node_modules/, loaders: ExtractTextPlugin('style-loader', 'css-loader!sass-loader') }

我正在尝试让 webpack 将我的 SCSS 构建为 CSS，但出现此错误：

/Users/bli1/Development/Django/CL/cherngloong/cherngloong/cherngloong/node_modules/webpack/node_modules/webpack-core/lib/LoadersList.js:60
    throw new Error("Element from loaders list should have one of the fields 'loader' or 'loaders'");
    ^

这是我的完整 webpack 配置：

var path = require('path');
var webpack = require('webpack');
var BundleTracker = require('webpack-bundle-tracker');
var ExtractTextPlugin = require("extract-text-webpack-plugin");

module.exports = {
  entry: [
    './app/index'
  ],

  output: {
      path: path.resolve('./public/bundles/'),
      filename: "[name]-[hash].js",
  },

  plugins: [
    new BundleTracker({filename: './webpack-stats.json'}),
  ],

  module: {
    loaders: [
        { test: /\.css$/, exclude: /node_modules/, loader: 'style!css' },
        { test: /\.json$/, loader: 'json-loader' },
        { test: /\.jsx$/, loaders: ['react-hot', 'babel-loader'], include: path.join(__dirname, 'app') },
        { test: /\.es6$/, exclude: /node_modules/, loader: 'babel-loader?stage=0&optional=runtime'},
        { test: /\.js$/, exclude: /node_modules/, loader: 'babel-loader?stage=0&optional=runtime'},
        { test: /\.scss$/, exclude: /node_modules/, loaders: ExtractTextPlugin('style-loader', 'css-loader!sass-loader') }
    ]
  },
}

Sokra 在此处提供了如何使用 ExtractTextPlugin 的示例：https ://github.com/webpack/extract-text-webpack-plugin/blob/master/example/webpack.config.js

如您所见，您的示例和他的示例之间存在一些差异。

  • ExtractTextPlugin 构造函数在 "plugins: [ ]" 数组中使用new调用
  • 在loaders数组中使用插件的方式是调用静态方法.extract()，而不是简单的调用插件构造函数
  • “loader 对象”中的引用是针对“loade r: ”属性的，而不是您所说的“loade rs: ”（loaders 是一个选项，但需要一个数组）

希望有帮助！
