2、解决过程
1）使用命令“npm install node-sass --save-dev”下载一个新的 “node-sass”文件
“Module build failed: Error: Cannot find module 'node-sass'”的意思是找不到模块的‘node-sass’文件，所以你要做的是去下载一个‘node-sass’文件，好吧，报错了。仔细看了一下，并借鉴 https://blog.csdn.net/qq_38401285/article/details/86483278 这个博主踩的坑，然后我直接做了第二步。

2）npm配置使用淘宝镜像 ‘npm config set registry http://registry.npm.taobao.org’
3）cnpm install node-sass --save，使用cnpm重新下载‘node-sass’文件
4）npm run dev ，重新运行项目。
