错误场景

在搭建一个项目的前端部分时，正常流程是首先要运行npm install，之后npm run dev，但是这里在npm install时，发生了这样的报错
截图如下

然后下面还有这样的错误
生成失败。

分析

首先有这几种办法，根据在网上找和对日志文件的分析结合，大多是在node sass上下功夫，那么是否是没有安装这个模块呢
1、 安装sass
在idea或者vscode的终端里运行命令

npm install node-sass

安装成功后，再执行npm install，如下图，成功
之后进行npm run dev

部署成功
2、 是否是没有管理员权限？
找到idea安装目录

赋予管理员权限

应用后就可以了

后续更新

后来在这个项目原先的说明里找到这个问题的解释，推荐的解决办法是这条命令

set SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass&& npm install node-sass

这个就是用淘宝镜像，会快一点
