WARNING in configuration

The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.

You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/concepts/mode/

这里提示问题是没有配置webpack的mode选项，默认有production和development两种模式可以设置，可以设为development模式，在命令行输入：webpack --mode development
