- building for sit environment...

解决方案:

在HtmlWebpackPlugin中添加入

chunksSortMode: 'none',

结果如下：

 new HtmlWebpackPlugin({
            filename: 'index.html',
            template: 'index.html',
            inject: true,
            favicon: resolve('favicon.ico'),
            chunksSortMode: 'none',
            templateParameters: {
                BASE_URL: config.dev.assetsPublicPath + config.dev.assetsSubDirectory,
            },
        }),
