执行npm install的时候报错：Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.1/win3


解决方法：

1.到https://github.com/sass/node-sass/releases下载win32-x64-79_binding.node。

2.回到命令行安装界面（nodes项目的目录下启动 命令行窗口）。

先输入 set SASS_BINARY_PATH=E:/win32-x64-46_binding.node


注意点：
1.可能大家会遇到gyp ERR! build error这时需要安装
先运行npm install -g node-gyp
后运行 npm install --global --production windows-build-tools 运行这个命令可能出能卡在图1的情况。
你可以到C:\Users\Administrator\.windows-build-tools 目录下查看一下是否成功安装成功。图2


2.可能遇到下面错误提示 npm ERR! Error: EPERM: operation not permitted,这时需要你用管理员的身份运行cmd的小窗口

最后是通过自己下文件安装运行成功的

//第一步
set SASS_BINARY_PATH=D:\douluoling\win32-x64-79_binding.node

//第二步
**//说明使用的是node 13.10.1的版本，不同的版本可能会出错**
D:\douluoling\ccb-df-fe>nvm use 13.10.1       
Now using node v13.10.1 (64-bit)

//第三步
D:\douluoling\ccb-df-fe>npm install node-sass

> node-sass@5.0.0 install D:\douluoling\ccb-df-fe\node_modules\node-sass
> node scripts/install.js

**//win32-x64-79_binding.node在github上下载的sass的版本**
node-sass build Binary found at D:\douluoling\win32-x64-79_binding.node
