完美解决VUE项目启动的时候报错HTTP error 404 Not Found

首先粘上log

F:\BackStage>npm i

F:\BackStage>npm i

> [email protected] install F:\BackStage\node_modules\node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.10.0/win32-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.10.0/win32-x64-72_binding.node":

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

> [email protected] postinstall F:\BackStage\node_modules\node-sass
> node scripts/build.js

报此错误是因为再项目启动的时候去github上下载node_sass文件的时候下载不下来导致的，此时只需要执行

npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

即可，设置npm的镜像指向淘宝就可以完成npm i命令。

如果内网中有node_sass文件也是需要设置指向，指向内网文件地址即可。
