错误：在终端中运行“节点框架构建”时找不到模块“扩展”

Question

我在编译.less文件时，我需要在终端中运行node skeleton build，但是发生了以下错误，而不是进行编译：

Building target: default
=============== ERROR ===============
{ Error: Cannot find module 'extend'

at tryModuleLoad (internal/modules/cjs/loader.js:551:12)
at Function.Module._load (internal/modules/cjs/loader.js:543:3) code: 'MODULE_NOT_FOUND' }

请告诉我如何解决此问题。
