Solo 项目打包 npm run build 出错

拉取最新版仓库代码，在进行皮肤升（qie）级(qu)开发时，使用
npm run build 报错！

具体：

$ npm run build;

> solo@4.0.0 build I:\idea_project\solo
> webpack --mode production

Browserslist: caniuse-lite is outdated. Please run next command `npm update`
   64 modules

ERROR in ./src/main/resources/skins/Bubble/css/base.scss
Module build failed (from ./node_modules/sass-loader/dist/cjs.js):

大意是 File to import not found or unreadable: vditor/src/assets/scss/classic. 同样，ide 开发工具也提示找不到依赖，引入的依赖命令如下：

 @import "vditor/src/assets/scss/classic" 

引入此依赖的文件位置在 /resources/skins/Bubble/css/base.scss;

另：我在项目中也没有找到 vditor/src/assets/scss/classic 此路径及文件；

大佬有时间看看，小弟在此先行谢过！
