我尝试使用 css-modules 设置自己的简单 webpack 配置。问题是我通过 css 类名称中的 css-loader 和 babel css 模块插件获得了不同的哈希值。

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const webpack = require("webpack");


module.exports = {
    context: __dirname,
    entry: "./src/index.js",
    output: {
        path: path.join(__dirname, "/dist"),
        filename: "index_bundle.js"
    },
    module: {
        rules: [
            {
                test: /\.css$/i,
                use: [
                    "style-loader",
                    {
                        loader: 'css-loader',
                        options: {
                            importLoaders: 1,
                            modules: {
                                localIdentName: "__[local]___[hash:base64:5]",
                            },
                        }
                    }
                ]
            },
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: [
                    {
                        loader: "babel-loader",
                        options: {
                            plugins: [
                                [
                                    'react-css-modules',
                                    {
                                        generateScopedName: "__[local]___[hash:base64:5]",
                                        autoResolveMultipleImports: true,
                                        webpackHotModuleReloading: false
                                    }
                                ]
                            ]
                        }
                    }
                ]
            },

        ]
    },
    plugins: [
        new webpack.EnvironmentPlugin({ NODE_ENV: 'development', 'BABEL_ENV': 'development' }),
        new HtmlWebpackPlugin({
            template: "./src/index.html"
        }),
    ]
};

似乎这个问题还没有解决，这里是开放的。基本上，您可以使用这个分叉包@dr.pogodin/babel-plugin-react-css-modules来修复与css-loader生成名称的兼容性。

这个想法看起来像：

{
  plugins: [
    "@dr.pogodin/babel-plugin-react-css-modules", 
    {
      generateScopedName: "__[local]___[hash:base64:5]",
      autoResolveMultipleImports: true,
      webpackHotModuleReloading: false
    },
  ]
}

或者我认为您可以通过自定义函数以直接在插件中生成哈希名称来解决问题here
