Question

我正在尝试将所有 css 提取到一个文件中，我正在使用 webpack2 并且我有 extract-text-webpack-plugin@2.0.0-rc.0，以下是我的代码

网页包

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


module.exports = {
    entry: './app/main.ts',
    output: {
        path: './dist',
        filename: 'app.bundle.js'
    },
    module: {
        rules: [
            { test: /\.ts$/, exclude: /node_modules/, use: ['ts-loader'] },
            { test: /\.css$/, use: ExtractTextPlugin.extract({ fallback: 'style-loader', use: 'css-loader', publicPath: "./dist" }) }
        ]

    },
    resolve: {
        extensions: ['.js', '.ts']
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './index.html',
            minify: {
                collapseWhitespace: true
            },
        }),
        new ExtractTextPlugin({
            filename: 'style.css',
            disabled: false,
            allChunks: true
        })
    ]
};

首先，您可以安全地const webpack = require('webpack')从您的 中删除webpack.config.js，这不是必需的 :)

您可以尝试不使用publicPath: './dist'&&use: ['css-loader']而不是use: 'css-loader'inExtractTextPlugin.extract()吗？
