Question

我的webpack loader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构建我的SCSS到CSS，但是我收到了这个错误：

/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提供了一个如何在此处使用ExtractTextPlugin的示例：https://github.com/webpack/extract-text-webpack-plugin/blob/master/example/webpack.config.js

正如您所看到的，您的示例和他的示例之间存在一些差异。

使用“plugins：[]”数组中的 new 调用ExtractTextPlugin构造函数
插件在loaders数组中的使用方式是调用静态方法.extract（），而不是简单地调用插件构造函数
“装载器对象”中的引用用于“loade r：”属性，而不是“loade rs：”，因为您已经放置（装载器是一个选项但需要一个数组）

希望有所帮助！

加载器列表中的元素应该有“加载器”和“加载器”。或者＆＃39;装载机＆＃39;使用sass-loader webpack
