webpackローダー配列にこのローダーがあります：

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

Webpack で SCSS を CSS にビルドしようとしていますが、次のエラーが発生します。

/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'");
    ^

ここに私の完全なwebpack構成があります:

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 はここで ExtractTextPlugin の使用例を提供しています: https://github.com/webpack/extract-text-webpack-plugin/blob/master/example/webpack.config.js

ご覧のとおり、あなたの例と彼の例にはいくつかの違いがあります。

  • ExtractTextPlugin コンストラクターは、「plugins: [ ]」配列内でnewを使用して呼び出されます。
  • ローダー配列でプラグインを使用する方法は、単純にプラグイン コンストラクターを呼び出すのではなく、静的メソッド .extract() を呼び出すことです。
  • 「ローダーオブジェクト」の参照は、「ローダー： 」ではなく、「ローダー：」プロパティに対するものです（ローダーはオプションですが、配列が必要です）

それが役立つことを願っています!
