Question

当我试图同时使用加载器进行语义-ui-css / semantic.min.css和普通的css文件时，我偶然发现了一些错误。当我独立完成时，我能够分别加载semantic.min.css和普通的css文件，但不能同时加载。

语义UI加载器（可行）

var webpack = require('webpack');
var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');

var config = {
    entry: APP_DIR + '/index.jsx',
    output: {
        path: BUILD_DIR,
        filename: 'bundle.js'
    },
    module : {
        loaders : [
            {
                test : /\.jsx?/,
                include : APP_DIR,
                loader : 'babel-loader'
            },
            {
                test: /\.(png|jpg|gif|svg|eot|ttf|woff|woff2)$/,
                use: {
                    loader: 'url-loader',
                    options: {
                        limit: 100000,
                    },
                },
            },
            {
                test: /\.css$/,
                include: /node_modules/,
                use: ExtractTextPlugin.extract({
                    fallback: "style-loader",
                    use: [
                        {
                            loader: 'css-loader',
                        }
                    ],


                })
            },
        ]
    },
    plugins: [
        new ExtractTextPlugin("styles.css"),
    ]
};

module.exports = config;

正常CSS文件的加载程序（可行）

var webpack = require('webpack');
var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');

var config = {
    entry: APP_DIR + '/index.jsx',
    output: {
        path: BUILD_DIR,
        filename: 'bundle.js'
    },
    module : {
        loaders : [
            {
                test : /\.jsx?/,
                include : APP_DIR,
                loader : 'babel-loader'
            },
            {
                test: /\.css$/,
                use: [ 'style-loader', 'css-loader' ]
            }
        ]
    },
    plugins: [
        new ExtractTextPlugin("styles.css"),
    ]
};

module.exports = config;

两个装载机同时（不起作用）

var webpack = require('webpack');
var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');

var config = {
    entry: APP_DIR + '/index.jsx',
    output: {
        path: BUILD_DIR,
        filename: 'bundle.js'
    },
    module : {
        loaders : [
            {
                test : /\.jsx?/,
                include : APP_DIR,
                loader : 'babel-loader'
            },
            {
                test: /\.(png|jpg|gif|svg|eot|ttf|woff|woff2)$/,
                use: {
                    loader: 'url-loader',
                    options: {
                        limit: 100000,
                    },
                },
            },
            {
                test: /\.css$/,
                include: /node_modules/,
                use: ExtractTextPlugin.extract({
                    fallback: "style-loader",
                    use: [
                        {
                            loader: 'css-loader',
                        }
                    ],


                })
            },
            {
                test: /\.css$/,
                use: [ 'style-loader', 'css-loader' ]
            }
        ]
    },
    plugins: [
        new ExtractTextPlugin("styles.css"),
    ]
};

module.exports = config;

Answer 1

这是因为您在加载器中为.css定义了两个测试。第一个测试是对项目中包含的所有.css文件进行评估，因此所有CSS都使用您的第一个加载器规则进行解析。如果要对.css文件使用两个规则，则需要对测试更具体。我将node_modules规则放在第二位。对于第一条规则，您可以使用static getDerivedStateFromProps(nextProps) { return { modalchildOpen: nextProps.modelStatus }; }确保加载程序跳过exclude中的任何内容，然后转到下一个加载程序。
