1、css模块化按文件名
//修改
{
    test: cssRegex,
    use: getStyleLoaders({
    importLoaders: 1,
    modules: {
        localIdentName: "[path]",
    },
    sourceMap: isEnvProduction && shouldUseSourceMap,
    }),
    exclude: [
    path.join(__dirname, "..", "node_modules"),
    path.join(__dirname, "..", "src/components/hehe"),
    ],
    sideEffects: true,
},
//新建
{
    test: cssRegex,
    use: ["style-loader", "css-loader"],
    include: [
    path.join(__dirname, "..", "node_modules"),
    path.join(__dirname, "..", "src/components/hehe"),
    ],
}
exclude include里面的路径不会被模块化，普通引入
其他的文件夹的css则会被模块化
