我第一次遇到这个问题是在尝试使用 ionic 时，它需要其模板的依赖关系。然后，当我尝试自己使用 npm 安装 node-sass 时，问题仍然存在。这是在Windows 10 Version 1703, both nodejs 6.11.3 and nodejs 8.4.0尝试过，最终得到相同的结果。 VPN、http代理都试过了，但没有成功。基本上，它是在说：
无法下载
”https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node"
当没有任何事情被摆弄时，它会说：
连接 ECONNREFUSED 127.0.0.1:443
当使用 npm set config proxy 时，它显示如下内容：
无法建立隧道
使用 VPN 时，它会永远等待：
节点脚本/install.js
或输出与没有任何改动一样。
报告错误时，您必须提供以下信息：

然后有人告诉我：
Well ECONNREFUSED很简单 - 你已经配置了 npm 来与
代理位于 127.0.0.1 (localhost) 端口 443 但代理似乎没有
对该端口处于活动状态。请检查代理/VPN 软件配置
- 端口号必须匹配。
但问题是我没有配置代理。我试过npm config rm proxy,and npm config delete proxy，我什至尝试使用它并设置一个代理，然后将 npm 指向该代理，就像我上面描述的那样，没有任何效果。这是 powershell 环境配置，以防万一：
⚡ rick@DESKTOP-1NVA03E ~ $reg = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
⚡ rick@DESKTOP-1NVA03E ~ $settings = Get-ItemProperty -Path $reg
