## 找答案 ##

看着这报错信息，看到有文件下载出现404，然后我又去找文件，结果搞hosts文件，我以为是python问题，然后重装各种版本python…

花了3小时，试了网上无数种答案，没有可以解决的

## 解决方案 ##

将sass-loader和node-sass的版本号提高到最新版，目前的最新版如下（2019年7月12日）  
“sass-loader”: “^7.1.0”,  
“node-sass”: “^4.12.0”,

如图所示，把package.json文件修改一下

然后再执行如下命令安装

npm i sass-loader
    npm i node-sass

## 2020-05-06更新 ##

这个问题出现的原因往往是 Node-sass 的版本问题，可能的一个原因是：因为版本太老所以会导致有的依赖项已经找不到了，公司有一个4年前的老项目就是这种问题，上面修改Node-sass的版本为4.12并不一定适合所有项目，可以多测试几个版本，如果上面的版本失败了可以试一试这个版本

"node-sass": "^4.13.1",
    "sass-loader": "^4.1.1",

## 2021-06-06更新 ##

Nodejs版本切换为13.6，这样才可以匹配上node sass的版本  
简单的方法是，先卸载nodejs，然后安装13.6版本的  
[Nodejs13.6版本官网下载][Nodejs13.6]

## 仍然失败怎么办？ ##

我的答案并不一定适合你，但是你要相信柳暗花明又一村。
