sass - Webpack ExtractTextPlugin 在加载 Sass 时抛出错误

Question

尝试将 sass-loader 添加到我的 webpack 配置中并遇到错误:

70% 1/1 build modules/Users/a557789/Documents/f/Portal/node_modules/webpack/node_modules/webpack-core/lib/LoadersList.js:81
        r.forEach(function(r) {
          ^
TypeError: undefined is not a function
    at /Users/a557789/Documents/f/Portal/node_modules/webpack/node_modules/webpack-core/lib/LoadersList.js:81:5
    at Array.reduce (native)
    at LoadersList.match (/Users/a557789/Documents/f/Portal/node_modules/webpack/node_modules/webpack-core/lib/LoadersList.js:80:27)

webpack.config:

var webpack = require("webpack");
var baseDir = "dist";

var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require("extract-text-webpack-plugin");

var path = require("path");

module.exports = {
    context: __dirname + "/app",
    entry: {
        app: "./main"
    },
    resolve: {
        extensions: ['', '.js', '.ts', '.css', '.scss']
    },
    output: {
        path: __dirname + "/dist",
        sourceMapFilename: "[name].map",
        filename: "[name].js"
    },
    module: {
        loaders: [
            //https://www.npmjs.com/package/webpack-typescript
            {
                test: /\.ts$/,
                loader: "ts-loader"
            },
            {
                test: /\.scss$/,
                loaders: ExtractTextPlugin.extract("style", "css!sass")
                //loaders: ExtractTextPlugin.extract("style!css!sass")
            }
        ],
        noParse: [ /angular2\/bundles\/.+/ ]
    },
    plugins: [
        new webpack.optimize.OccurenceOrderPlugin(true),
        new ExtractTextPlugin("style.css"),
        new HtmlWebpackPlugin({
            template: "../index.html",
            inject: "body"
        })
    ],
    devtool: "source-map"
};

我已经为 extract() 调用的参数尝试了一系列不同的选项，但没有成功。任何帮助将不胜感激。

Answer 1

而不是使用

loaders: ExtractTextPlugin.extract("style", "css!sass")

你应该使用

loader: ExtractTextPlugin.extract("style", "css!sass")

相反。

在这种情况下，错误不是特别具有描述性。
